Ah I noticed this on Jerboa as well, there isn’t an option yet to make it a default feed. I have to manually select Subscribed (Lemmy) / Home (Connect) everytime I open up the apps.
I reinstalled Connect just now and am making this post from it. There must have been an update since I tried it because now I can make it only show me communities I’m part of. I’m also able to block communities. And for some reason it shows me your deleted post whereas other things have shown it as deleted. Although I do remember something about deleting stuff not being consistent on lemmy.
The biggest problem I’ve seen is people posting from your instance aren’t even getting the replies from the main one synced. Viewing the thread there shows 3 or 4 posts while there’s at least 10 and who knows if there’s any missing from other instances.
