Dropbox authentication problem

Hello sir, i am unable to login into my cryptomator vault stored in dropbox. More than 2 months , i have been signout. Please fix it as soon as possible. If i try to download that folder and try to add that vault, it shows root vault in cloud error. @SailReal

Can you please enable debug mode, reproduce the problem and send us the log file? How do I enable debug mode on Android?
