Duolingo won't add friends
I tried adding my friends and following them but every time I refresh the page it says I didn't. I tried both on the mobile and desktop but nothing works. They added me fine but for me, it doesn't work.
I doubt Duolingo deleted them. Particularly with the latency issues lately sometimes discussion pages won't open (or potentially things you've thought posted actually didn't). Save a link to a discussion you start if you're concerned. They can also disappear b/c of accruing 5 downvotes. That's not Duolingo; that's users probably deeming your discussion to have been in the wrong forum or repetitive. Such posts aren't deleted, but you would need a link to access them: either an e-mail, a notification, or a bookmark.
