Greetings All,
I'm posting here with the hope that I'll learn a solution for my issue. Today's the third reading from a new Sleep Pad. I've attached the respective three nights sleep graphics. Here, the App. correctly classifies all the segments up to the last interruption, a trip to the restroom. When I return to bed I try to fall asleep, in these instances, I remain awake and eventually get out of bed and start my day. The very last segment indicated by the red arrows should be recognized as "awake", just like the very first segment when I initially go to bed.
I've already sent a similar message to Withings tech. support concerning this issue. They have already advised me that I can edit the "fall asleep" and "wake up" values. I don't see that as the problem as the segments are present; they just have the wrong tag.
Setup for the device and software took only a couple of minutes. Firmware version's 2291.
Perhaps someone has experienced this and found a solution? Please let me know. I'd like to see this work correctly.
Sincerely,
Eric
Added 10-23-2021. The newest graphic shows the same error...the last segment after the "interruption" is coded as "light" when I was still in bed after returning from the restroom. The coding should be "awake"... because I did not fall back to sleep.
I did try editing the wakeup time, but the "interruption" and event following it were deleted and an "edited" symbol was added. I changed the value back to its original, app-reported state.
Thoughts anyone?

My train-wreck continues. The pic of Oct 24 shows where an "interruption" would have been placed if I tried to return to sleep after a restroom visit, but I didn't; starting my day from this point. This reading is likely correct.
Oct 25 shows three segments where, after a terrible day, I had gone to bed, tried to go to sleep, tossed, and turned until about midnight when frustration won and I got out of bed. These three segments should have been coded otherwise as I was in bed but awake.
Withings tech. support got back to me this morning, stating that their development team's working on the issue. I hope there's a solution soon.

Huzzah! The Sleep Pad got it right :-D Now if I can actually sleep longer than this consistently, that would be nice.
Added 10/27/2021:
Here's last night's chart. The two segments after the first interruption (restroom) should be classified as "awake" as I returned to bed and tried to go back to sleep. Not long after this point, I got out of bed. At about 2:10 AM I returned to bed for a second attempt to sleep. Unsuccessful, I got back out of bed at about 2:50 AM to start my day. The very last segment should be classified as "awake".
I'm going to read more about that "sensitivity" adjustment. Perhaps that will have an effect. I'll comment on the observation on the next edit.
Added 10/28/2021:
Appears correct, huzzah!
Sensitivity setting: per the user's manual, the pad detects me in bed throughout the night, therefore, I do not need to increase this setting.
Added 10/29/2021:
Appears correct. I hypothesize that the mid-sleep restroom visits involve my recently diagnosed Type 2 diabetes and that my extended sleep interruptions are related to the fasting regimen discussed in my previous Doctor's consultation. Although, I don't have enough evidence at this point to confirm either case.
Added 10/30/2021:
The last segment should have a segment as "awake" as I was for a minute or so before getting out of bed. Perhaps there's a minimum amount of time to elapse before a segment is depicted?
Added 10/31/2021:
The interruption is listed in the details but is not depicted in the timeline (restroom visit). I did return to bed for more sleep but was unsuccessful; getting up for the day afterward. There's either missing segment(s) (a gap showing out of bed) or a misclassification near the chart end.

The latest sleep chart... looks correct:

Looks right to me:

Here's the latest chart...looks right - 
Added 11/04/2021:
Last night's reading. Is it usual to have deep sleep immediately before getting out of bed? Otherwise, the chart looks correct?
Added 11/05/2021:
That last segment shows me at "light" sleep, although, while I was in bed after returning from the restroom (the second interruption,) I was awake lying quietly trying to return to sleep. That effort failed and I eventually got out of bed around 2:06.
Added 11/06/2021:
After the second interruption, I tried to return to sleep... unsuccessfully. Although I was in bed, I was awake until getting up near 2:07 AM. Those two last segments should show as "awake" instead of "rem" or "light sleep". As an aside, "total sleep" and "in bed" should read 04h05 and 04h59 respectively.
Added 11/07/2021:
Like the night previous, last night's chart follows the same pattern, the last two segments show as sleeping types when I was in bed, awake, but (unsuccessfully) trying to return to sleep after the interruption/restroom visit:
Obviously, the sleep time and time in bed numbers would update. Readings were taken every night since installation two weeks ago. I'd sure like to hear of any (cause) of this misclassification issue.
Added 11/08/2021:
This will be the last chart appended (chart looks OK). I'll continue to look for a solution and archive my charts, but with occasional monitoring of this post.
The track results have not been encouraging. I have until the end of January 2021 to decide if the Sleep Pad is a good fit for my situation. (It's a question of data classification accuracy.) 
Best wishes and good luck to you,
Eric A.
