This article explains the possible reasons you may have been removed from your club.
Reasons you may no longer be in your club
If you find yourself outside your club unexpectedly, one of the following happened:
You left voluntarily — you may have tapped "Leave Club" without realising it.
You accidentally requested to join another club — sending a join request to a different club removes you from your current one.
Club Guard removed you for inactivity — if your club has Club Guard enabled and you were inactive beyond the set timeframe, you were automatically removed.
A club leader expelled you — the club leader or a co-leader removed you from the club.
Can I rejoin my old club?
If you were removed or left by mistake, you can search for your old club in the Billionaire League screen and request to rejoin. Whether you are accepted depends on the club's settings and the leader's approval.
