Hello @Peter !

I've checked the limit by the membership and it works as it should on my side. Yes, it is possible to find the closed group by the keyword, but the found items will be marked as "Private" and it would be impossible to see it without rights. The point about:

The defined membership level cannot see the group in ''groups-home''

means that only public groups are shown on the Groups home page. Any visibility limits drop the group frmo there.
