So I did the update this morning with no problems like always. I did the twrp way like I always do but I just noticed I can't send MMS anymore. I'm rooted and on straight talk. I went to check my apn and for some reason it changed. Tried to put the correct apn in and it won't save and the one that's set up is all grayed out so I can't change anything. Anyone know of a fix for this?
