Alta HR blank display

[ToriB21]

Last week my Charge 3 screen went black although it still vibrates and tracks steps. I tried all the troubleshooting steps without success and after contacting customer service I was told that my Charge 3 is not under warranty so I pulled out my Alta HR (which was only replaced because I received the Charge 3 as a gift). I charged the Alta HR and followed the set up process on the app without problem, however a few hours later the screen on the Alta HR also went black! It seems to me that if the black screen is a consistent problem across multiple Fitbit devices then there must be a software issue. In case it matters, I am using the Galaxy S9 to sync devices.

I am really frustrated that I have had 2 Fitbit devices go from working perfectly to being completely useless in less than a week without any reason or user error. I am curious if anyone else has experienced similar issues. There's no way I'm buying a new Fitbit device just to have it join the graveyard of black screens.
