HubHive Testers

I’m trying to post pictures for advertising our hive and they aren’t loading there or general announcements. Does it take extra time these days? Or are there limits to how many I can upload at a time? I tried 5, then 2.

I'm in Nataleen's word of wisdom hive, it shows that I've joined the group. When I try to open a post, it says what it says in the attached screenshot.

Can I uninvite people to a hive? I accidentally invited some people to my tball hive that I didn’t pick their kids and need to undo it… when I was typing names and went to invite, then auto-incorrect turned on with a delay and changed the search name as I was hitting the invite button (a screen recording would make more sense for what I’m trying to say… but I didn’t mean to invite the two people in this screenshot)
