One day Texts stopped coming through on my iphone 12, but only from certain contacts. There are no blocks, one is my boss who can't get a hold of me via text. This is only the primary text app on the iphone. Whatsapp works fine. Verizon IT could see it was happening but couldn't find the problem. It's frustrating and if not resolved, I'm going to leave Verizon. Is there anything else I can try. I've done all the resets and deletes asked of me but nothing has worked.
