Collections All Reset

All of my collections are gone without me deleting them. It didn't affect my favorites but all the custom ones disapeared for no reason. Is there any way to restore them?

Even the built in read later isnt showing up in the drop down menu when I try to add to collection.

If I create a new collection it instantly disapears

Deeply apologize for this issue. Currently working to repair the problem. Don't worry, your collections still exists, there was just some code changes that have resulted in them not being grabbed from the database properly. Should be fixed very soon. Again, sorry for this issue.

Edit: Collections should be working again now.
