I need faster and reliable sync.

I tryed to use proton drive to store my encrypted password database (keepass) but if add a new password and save the archive on my computer and after 30s 1 minute i try to reopen on my android phone i stil have the old version

so i have to use dropbox... it works flawlessy, the same moment i save my file on a device the new version is avviable on the other but it's US based and i don't like that

also please consider to a sorto of API for third part apps.... i use duplicati backup and i can directly save the backup on Onedrive, AWS, Gdrive and others... but not on protondrive
