I have and ipHone Xs Max; IOS 13.3.
Everything was fine with my BPM (software version 421). I was reading my blood pressure twice a day during the last 30 days.
Now it does not work anymore. It does not inflate. It goes untill 30-40 mmHg and it cannot go any higher.
I've tried everything. New batteries. I´ve reset the BPM. Installed it again and again.
I even installed it from scratch in a iPad Pro I bought 10 days ago just to check it with a new IOS device.
Nothing. Again, it does not inflate. Since two days ago.
