Let's face it: the app has been abandoned for longer than is acceptable, especially at this price level. It's no longer working correctly on newer Lemmy versions, and there's no indication the dev is still active.

Yes, he worked similarly during Reddit times, but a) Sync was much cheaper back then, and b) Reddit didn't change as much.

Right now, to unsuspecting users Sync seems great given the 4.9 star rating on the Play Store. They'll possibly buy this app before noticing that it's subtly broken.

Please consider giving Sync a bad rating, but if you do so, explain why. Write about the broken functionality, so others don't fall into the same trap.
