I don't know if I should keep the Pro Move

It's nice to use as a daily journal, but I hoped to be able to use it for more than that. I've installed Remanager and all. KOreader and other small things. The biggest thing for me was bluetooth, because sometimes I need to type.

Today was the first time that I connected a keyboard and after the keyboard went to sleep, the device didn't want to connect anymore. So I thought, let's restart my reMarkable. ..And every adjustment I have made to the device is gone now. The bluetooth icon is completely gone. KOreader gone.

What should I do? Is there a reliable way to fix this or should I start looking for other devices that will be more suitable for my use case?
