I just updated Amber and now the problem seems to have been solved.
Before, when I was composing a note, every few characters Amber would slide in and out automatically, it was a mess.
The nip44 problem is different, it was already there, the remember flag is not respected. 

 Do you know what version you were using before updating? This issue was supposed to be solved a while ago 

 Sorry, I didn't take note before updating.
Maybe I was just using a quite old version.
PS: an integrated notification of new versions could be a good feature for sensitive apps like Amber. 

 That would be annoying. Glad it's fixed.
