I hate to get rid of editing if there is already no way to bin or delete a post. The attachments are capped very small, but somehow it’s being offered in the edit screen? I always make typos and go back to edit.
There’s a similar issue in the age verified forum. At first the attachment limit is 2MB, but when you go in to edit, the attachment is capped at 512KB. This looks like editing might be linked to the permission to add a 512KB file!
