Can't join a group on FB?

[Melody J]

After joining a few groups, the join option only says "cancel request" every time I click to join a group. That's all it says on every group I try to join! Any thoughts on why the join group option is gone? Do you have to wait a while before trying to join more groups?

You can join to 300 groups in Facebook. if you have click join button of a many groups per day, then it may be a block otherwise report your problem to Facebook
