It’s been pretty good. I have noticed the default sort order (‘Active’) results in the feed getting stale pretty quickly. Changing the default to ‘New’ has been a better experience so far, at least at the current level of activity.

I have had a few issues subscribing to communities on remote instances (i.e. not showing up in search, or showing up but with an empty feed when content definitely exists when I check the web UI) - this does not appear to be an SFW/NSFW issue, and some communities from the same remote instances appear correctly.

Hard to tell if this is an instance/protocol issue, or an app issue.

It should be in the profile menu on the top left. Perhaps LJ is rolling it out selectively.

I bought it last night and it was half the price in OP’s screenshot. Either it has gone up, or again perhaps there is some A/B testing going on at different price points.

There is, at least on the version I’m running (beta 26). It should be present in the profile menu on the top left.
