Tapping the post form submit button results in an error that says to pick one of the ten communities listed which I guess are those that horizontally scroll under the "community name" form field. So I guess I can only post to those.. not sure why it's limited. It's a bug unless I missed a new setting.
I had to create this post using Jerboa ๐
Connect version 1.0.69. Also applies to 1.0.71.
If that's the case then that's a bug too, that's not a requirement in Lemmy. You can post to any community regardless of subscription.
However, I am subscribed to this community. If Connect is incorrectly requiring subscription to post then there's a bug there as well.
I was able to post here via Jerboa after all.
