I started having the same problem since the "update". It's doing it on EVERY ACCOUNT, each time. I've re-entered my passwords dozens of times, but it still keeps asking on each account. Total pain in the ass. I wouldn't have bothered with this program if I wanted to do things manually.
I'm using the app on a Mac. I only had syncing problems with 1 account always asking for authentication prior to the update. I'm surprised no one else is complaining about this issue.
I'm having the same issue ever since I upgraded to the latest version on iOS. It's super irritating to have to enter my password every single time for every account. I too thought that maybe it's a new setting they added but no such luck. I hope they fix it soon!
Yes same problem for me. Have to Authenticate every time. Arghhh
