iMessage not working when on a phone call
Ever since I upgraded to my iPhone 11 I have been unable to consistently sending iMessages while on a phone call. Messaging works fine, unless I am on a phone call. I am connected to wifi and a majority of the time when I am on a call and try to send a messages it goes as a green text message. Occasionally after the first message the send arrow will turn blue and then messages will sent via iMessage. When it remains green of course I cannot send photos.
I have the latest iOS and have spoke with my carrier. No luck.
iPhone 11, iOS 13
