I used Diarium on win10 (got it from Microsoft Store) a year ago or so, and I have the pro version for iOS. At that time, it synced ok. Right now, the sync is not working though. I usually use OneDrive or iCloud. But whichever I choose, it just simply pop up an "Error while syncing diary", saying a connection with the server cannot be established.
I cannot find where to reset the sync setting. There's no place to type in or change any login info for those services. I deleted the software and installed it again. I also tried disabling the sync, then enabling it again. But when I click sync, it just goes straight into sync error (not even asking for login info).
My app is 3.0.46.0. Any suggestion on how do to fix the sync in this situation?
