I used Voyager for a while and here are the issues i noticed before I switched to another app (which also has issues):

1. Gestures for actions tend to take big motions, bigger than is comfortable to me, and the difference between actions is small. Like, I need to swipe very far (and not too fast), and then within a few millimeters, it goes from upvote to downvote. In the end i was just wishing for buttons considering how much work was to reply or downvote.
2. The combo of auto-marking posts as read when scrolling and hiding read posts doesn’t work too well. I frequently refresh my feed to only see stuff I’ve already seen and the posts stick around until I manually click then, go back and refresh. When I drag down at the top of my feed to refresh, I want to see posts I haven’t seen before. Refreshing 2-3 times and seeing nothing new…i don’t think anyone expects that from a social media app. Nearly all Lemmy apps seem to have trouble with this behaviour.
3. I don’t think it’s a great idea to make “click = comment and thread disappears” the default. I often did it by accident and was very disorienting.
4. I would often accidentally swipe/touch something, not realize what, and end up at my feed, the post I was looking at entirely gone, and no easy way to go back. To this day I’m not sure how I did that, but each time it a bummer to give up the post I was reading.
