Personally, I disliked Sync for Reddit and did not use it. And, personally some of those quirks still bother me with Sync for Lemmy.
But…Jerboa, Connect, Liftoff, etc. currently also don’t work as well or are as customizable as I’d like. Liftoff is definitely the closest, though, and I still switch back to it after each update to see how it is progressing.
For now though, Sync ticks more of my hot button boxes despite its flaws than any other app I’ve tried (so far).
