Not entirely sure if this is a Liftoff issue or something else, but when browsing posts after opening the app, the app refreshes and scrolls back to the top of the page seemingly at random. It makes using the app difficult, since it does so without prompting in the middle of reading througu the posts.
I am seeing similar behaviour too. Not sure if the update to Lemmy 0.18.3 or something caused it or Liftoff did.
