This was a bug in v0.4.2.4, I just released an update that addresses this and a few other issues caused by the same bug. You should be able to access all the community information, and actions from community feeds now.
Currently it’s a little buried, but hopefully could get uprated. You can get to that by going to the community, click any post, click the three dots, click Community dropdown, and then either Sidebar, Unsubscribe, Block, etc.
