I just released Unread 3.7.3 for iPhone and iPad through the App Store, and build 400221 of the Unread for macOS beta through TestFlight.

These updates fix a bug that caused articles in Fever accounts to not get saved correctly. Saving of the article would not be sent back to the Fever server, and the article would become unsaved locally after refreshing the account. This bug did not affect customers using Unread Cloud, Local, Feedbin, Feedly, Inoreader, or NewsBlur accounts.

This was clearly a serious bug. I am sorry about this. I added automated tests to help prevent similar bugs from appearing in future versions of Unread.
