Folks, I just loaded 10.3.1 (over the air from OnePlus) and now I can't receive any MMS messages on the Google messenger I had the exact same issue when I loaded 10.3.0. I called OnePlus support and they wanted to factory reset my phone.(I refused to do that and finally found another way via a 6T forum). They (and I) went to Verizon and got a new SIM's chip and it fixed it. I called OnePlus and asked that they give that information to others instead of telling users to do a full factory reset. They apologized and said the rep should have looked for other solutions. BUT..... No I have the same issue with 10.3.1 NO MMS's can be received. Very frustrating....
