Impossible Can’t even register device. I purchased a blood pressure cuff and the instructions were incorrect. Finally discovered that you need the app in order to connect via Bluetooth. Great. Downloaded app. Registered. Attempted logging in. Invalid password. THAT I HAD JUST SET UP. I reset it. Attempted to log in. IT HAPPENED AGAIN. After the third time carefully setting up my password and it failing, my blood pressure is greatly elevated. Thanks a lot for nothing.
