I’ve not had any luck joining any of these rooms. I click the link, continue with Element (the web app), I can see that I’m logged in and can access a room I’ve already joined (for moderating another community), but for these rooms, I’m just getting:
#lwgeneral:h-y-p-e-r.space is not accessible at this time.
Try again later, or ask a room or space admin to check if you have access.
M_UNKNOWN was returned while trying to access the room or space.
If you think you’re seeing this message in error, please submit a bug report.
