Messages 'failed to send' when they do actually send
All of a sudden all of my messages "fail to send" and i get the little red exclamation mark aswell as the notification saying the message was not sent however the messages actually do deliver (both iphone and android) however they are slightly delayed compared to normal.
I contacted my provider and they said it is not an issue on their end as the messages are actually delivering and insist its an iphone issue.
I have force restarted my phone multiple times, turned areoplane mode on and off, closed all apps etc. and nothing seems to work.
iPhone 13 Pro, iOS 16
