Hi there! I understand your Great Courses Plus app on your iPhone seems to be forgetting all the episodes you've watched, and that's happening suddenly and right before your eyes? I'd love to help get this sorted. Just to clarify, is this happening with all courses or just specific ones? Also, are you logged into your account consistently, and do you use more than one device to access the app?

Meanwhile, let's start with some basic steps tailored for your iOS 18.7.1 device:

1. Check Your Internet Connection: Make sure your iPhone has a stable internet connection as syncing your watched episodes relies on it.

2. Log Out and Back In: Sometimes, the app might fail to sync properly. Try logging out of your Great Courses Plus account in the app, then log back in.

3. Force Quit and Restart the App: Swipe up from the bottom (or double-click Home if your phone has one) to view open apps. Swipe the Great Courses Plus app off the screen to close it, then reopen it.

4. Update the App: Check the App Store for any available updates to the Great Courses Plus app, as bugs can be fixed with updates.

5. Clear Cache / Reinstall: If the problem persists, deleting the app and reinstalling can clear any corrupted data that might cause this forgetfulness.

If these don't fix it, we could explore app-specific settings or account syncing issues. Have you noticed any recent app updates, iOS updates, or changes in your subscription status?

Let me know what you find, and we’ll take it from there!

All of a sudden , the app forgets all my watched episodes. It erases them before my eyes!
