Gitlab has introduced a five-user limit for free groups

Just got an email from GitLab about a group I'm part of that has more than five users. The docs linked says "For existing namespaces, this limit is being rolled out gradually. Impacted users are notified in GitLab.com at least 60 days before the limit is applied.", however upon checking the group in GitLab, we are greeted by a big red box stating "Your top-level group [group] is over the 5 user limit and has been placed in a read-only state."

Also got an email but interestingly the most populated group I'm a member of has 4 users in it including myself. It did mention that my "top-level" group has reached the 5-member limit but it references a numerical ID that doesn't match my user or any of the groups I'm member to.

There may be a glitch with this rollout.

Yeah, I got the same email. I am in one group, and that group has one other person in it.
