I know you hate that word intermittently, but this is what is happening...
I have had several reports in the past month of group members not being able to see the comments & comment box when they visit a group discussion.
These are members of the group, they are following the discussion and they have recently commented and often updated comments on the discussion.
They have reported getting an email notification of an update to the discussion, following the link to the comment, but finding only the Group Discussion header visible (see screen shot). after a few hours, they can return to the discussion using the same link and all is as it should be, with comments visible and they are able to add comments again.
I have not seen this myself, but at least four members have reported it in different groups and discussions and I believe it is seen on Mac, phone and tablet, with Safari and Chrome browsers.
Has anyone else heard of this?
I'm aware that time limits can be applied to commenting, but this has been disabled on our site.
