So I’ve been having this issue with the mobile (iOS) version of the site using apple’s safari. A lot of times when I try to write something, then either deselect the text area or switch to something and back, the entire site will lock up, no buttons or videos will load at all, and the only way to get out of it is to refresh. I haven’t had this happen on other sites or the Desktop version of the site. However this may be a bug in the forum software itself, but I haven’t tested it anywhere else.
There is it really a way to have a picture of what is happening, since it is entirely input-based.
