could you please help me? I am not able to use Messenger, because after logging in, it says ,,Sorry, something went wrong'' and nothing else but that they are trying to fix it.
I have tried to log in Messenger on both notebooks, which we have at home, and it was always the same. Nothing changed even after deleting history and logging in again.
There is the same problem also in the Messenger application for desktop.
Because I am not able to open Messenger, I can not sent them message, that I have some problem. I am also not able to sent them (Facebook support centre) message with Facebook, because I have not any Facebook account anf therefore I use Messenger without facebook.
Other websites such as gmail etc. are ok, therefore it could not be problem with internet conection.

Thank you for any help.
