Invited users become owner of the group chat by default
I created a group chat and invited another user, the invited user is owner of the group chat and I see no way to change that.
Due to an influx of spam, we have had to impose restrictions on new accounts. Please see this wiki page for instructions on how to get full permissions. Sorry for the inconvenience.
