So I recently set up an account for Facebook Messenger on my phone, though not wanting to go through the hassle of Facebook I set it up with a 'phone number (although I did later get an account for Facebook). However I find that whenever I go to add new people on Messenger it won’t work - I will find the person, hit add in Messenger, send a message, but they won’t receive anything and all I get is a little red circle with an exclamation mark coming up.
I’ve tried reinstalling, updating my phone, checked internet connection, etc. For people I add via a scan code or phone number there is no problem messaging, and if they send me a contact request it will work.
Does anyone know how to fix this problem?
