Its super slow, everything, on one device samsung 7edge) it lets me invite one by one, because if i take longer, to put more names in, then it refreshes and sends me back to the thread.
Othe the other device (samsung A13) it doesnt let me invite anyone, it just refreshed but one the app returns to page, which takes ages, tgen im still on the same stream page.
