Problem description: Cant save some random contacts.
They can save me and message and see my profile fine, but when I save them as contacts I can open a chat with them or I crash, and it shows Send Email as first option instead of send offline message. I can not see their profiles or message them without them messaging me first. It says theyre not in my contacts at all times and when I try to edit their contact it says they couldnt be saved.
What has been tried so far: Tried deleting and readding several times over on both sides too, relogging etc.
Messenger version: 8.5 and 8.1 both had the problem
Windows version: 10
