I am having a very strange issue while group chatting on my new 6p. First of all, group chatting doesn't work at all on WiFi (Verizon, BTW). I've been scouring threads to figure that out, but it always seems to lead into an argument about what carrier is better. The actual issue I'm having right now is that every group message I receive in the native messenger app is received both in the group chat and the individual chat thread. Even stranger still, is how it appears in the individual chat as a "MMS download failed" error. And it gives a new error for every group text sent. As you can imagine, a ten minute group chat session leads to several ruined individual threads, covered in dozens of "MMS download failed" error messages. Anyone else having this? Is there a fix besides downloading a secondary texting app? Thank you in advance.
