A week ago Monday, the Sense 6 update hit my phone. Once loaded, I could no longer send MMS over WiFi, stream Google Play Music over WiFi, access my content on Google Play Books, or back up my pics to Google Cloud over WiFi. After several days of e-mails back and forth with HTC, it was determined that I had to perform a Hard Reset and lose all my information. This after clearing the cache, re-booting, various Safe Mode re-boots, etc. Nothing worked. I finally gave in and performed the hard reset. Now, the only thing NOT working is MMS over WiFi. I've tried other WiFi networks and still no MMS functionality. After about 10 minutes, I get a red triangle next to the message and an error notification, "Generic Network Failure."
This is going to start costing me money. Like so many of us, I no longer have unlimited data. Now, every time I want to send an MMS, I have to use my data plan. Not cool. I'm hoping that someone sees this and is working on the problem. I love my HTC One (M7), I really do. But, we're talking basic smart phone functionality. Without it, I'll be looking for another phone, and perhaps even another carrier. I'd prefer not to do that, but so be it. Please, Verizon, a little help?
For what it's worth, the MMS does this first. Notice the little MMS icon with the clock lower right...it just hangs there first...and sorry about the shoe pic..png)
Next, it does the Red Triangle thing...

And that's all I know. Perhaps someone here, or a kindly VZW employee will see this and take pity. Thanks!
