I attempted to contact support when I merged two accounts and all of the content from one disappeared. My messages went through and I got a reply a few hours later (which showed up in my lock notifications) but then when I went to read the reply it wouldn’t open. (My posts and credits did not get restored.)
Any time I try the Contact Support or Help and FAQ buttons I get a screen that says “Something’s gone wrong” “Content could not be loaded” and reloading the page does nothing.
