I have been having lots of issues with entire posts in groups disappearing after I edit. Usually in Our Daily Dinner. We have long conversations, and I have noticed several times recently that I will go back to edit a comment, by maybe adding just one sentence or thought, and I click "save". Then, when I go back to the group, the entire post will be gone! I have started double-checking to make sure that nothing in the post is highlighted, etc, before I click "save". I guess for now the fix is to not use the "edit" button. Is anyone else having this problem?
