I use Flashcards Deluxe Lite(free version) on iOS and Android devices now. I have a problem from syncing the database on Dropbox. There is an error. “Server error : expired_access_token/.”
i re-login on Dropbox, then it’s ok in syncing. But after several hours, it says same error again.
I have noticed the Lite’s version is old. Would you check on it?
