Help needed.

I have a club on FH4 and I am admin on another club for FH3 . So when I try to join a horizon club (which is mine but my co leader set it up for online adventure- FH4 ) it says I must leave a club to join this one? I only have 1 I own and 1 I am admin so why can’t I join another as a member. Is 2 the limit ? I can request to join it, the owner accepts, then I get another invite. Always get the same message, I can’t join. Any ideas ???

Also I can’t create on as I always get server error hence why my co leader set it up. It’s really frustrating.
