Shoot. There was definitely a bug in one of the releases that could cause your feeds to disappear, but I thought I had resolved that.
The app uses a local database to store your feeds and feed content and at one point I changed the location of that database so that the database could be shared between the app and the Safari extension. The “disappearing feeds” bug was (is?) caused when under certain circumstances (that only affected some users) the app fails to move the database from the old location to the new location, and instead it creates a new database in the new location. The good news is that in those scenarios, the old database is still on the device. There is also no code path that can overwrite the database – so it shouldn’t be possible to have deleted the database.
I’m hoping to have a new TestFlight release ready by the end of the week or early next week, and I might add a diagnostic tool to help troubleshoot this issue. The results of that diagnostic might help me restore your original database and fix this issue.
It happened on mine again too. I don’t know if this has anything to do with it but… This time it was when the public app became available on the App Store. My phone automatically downloaded the public version because I had put it on my wishlist. When it did that it erased my TestFlight version. Could that have caused the feeds to disappear or be erased?
I downloaded the TestFlight version again but the feeds were still gone.
