I was able to uninstall the upgrade via the app proprieties. That was the way to go for me. I cannot afford to not have my notes in all my devices.

Thats a really dumb decision. I use a Note9, a Tab S4 and ocasonally a Tab A 2016. Now I cannot have access to my notes across devices. I'm gonna try to uninstall this version and install the previous one. Why Samsung, why?
