Occasionally, my phone will stop receiving MMS messages. Non- iMessage texts containing a picture or in a group message will all of a sudden show up all at the same time hours or even days late. I have the Messages+ app from Verizon and can see those messages arrive through that but they won’t always come to my phone in the native Message app until much later. Anyone else having this issue? It only started for me when I upgraded to the 11 Pro last year.
