Yesterday I posted in a group, and got a delivery error message...since then I haven't been able to see any posts in that group...anyone elses or mine...my posts are going through, as i asked a friend in the group if she sees my post...so it goes through...i just dont see it or any responses...i do still seem to be getting the notifications from the group though... Any advice on how to fix this issue? nothing like this has happened to me before...i've had delivery failure issues before, but not with these kinds of results.
