[Sync iOS 2.4.8 - Can't add folder by key]

Is it possible that you entered the key incorrectly? Where did you obtain the key? If it was copied & pasted from an email, did it copy correctly? (i.e. if the link/key "wrapped" onto a new line in the email, when copying it may have inserted a space/copied as two lines instead of one, etc)

 

I would not seek support here if I have not verified it with multiple keys and multiple clients. It is serious.

a newly installed Sync 2.4.8 (https://itunes.apple.com/us/app/id1126282325) from China App Store failed to add key. 

Why is that? Meanwhile, add folder by qr code works fine.
