MyFitnessPal Doesn't Sync

Wondering if anyone has had any success getting MFP to sync calorie info to the HealthMate app? Mine worked for a day or two after I set it up but then no amount of disconnecting/reconnecting, force quitting apps, checking web connectivity, etc. has been able to get my calorie info to appear on HealthMate. I am using the latest versions of both apps on Android. I also saw something about the calorie data transferring 12 hours late but my last several days of calorie info are all blank in HealthMate so that's not happening to me (and if it was,it would make the MFP integration feature functionally useless). Given how much better/more accurate HealthMate seems to be about keeping track of calories burned, I was hoping to take advantage of this function but so far I haven't had much luck. Any advice?

Quick Update: I logged into HealthMate app this morning and it acted as if I never connected the apps, despite having done so several times yesterday, so I had to grant permissions all over again. Needless to say, still nothing is being synced between the two applications. Any insight into what's going wrong here would be appreciated!
