B asks a question in a private group (who can view= By invitation only) where A is NOT a member.
A gets the question in his newsfeed (MUST NOT BE BECAUSE THE GROUP IS HIDDEN)
If you check the same with newsfeed posting it work - A does not get the post of B in the private group
PLEASE FIX IT BECAUSE I HAVE A PRODUCTION SITE WITH HIDDEN GROUPS!
Thanks, Christian
