Not receiving messages

I am having this issue as well.  I realized it was happening a few days ago, but not sure how long it has been going on.  I get maybe 5-10% of MMS messages, and that's it.  Seems completely random.  I put my SIM card in an old iPhone and I get all test MMS messages that are pictures or group text replies.  Everyone gets my messages.  I did a factory reset on my Pixel 2 XL with no restore, issue still happens.  Does anyone have any updates on this whether it is a google/android or AT&T issue?  I will probably try to give AT&T a call today.  Already have a case open with Google but haven't gotten anything useful from them yet.

Similar to @tkr843243, I went back to my Nexus 5X this week. I have not been losing any messages now, I verified this at the end of the day with my groups. Plus my group texts make sense now.   So it is definitely something between pixel2 and ATT. Hope a solution is published soon. I miss my pixel2, its better than the 5X.

Another update.  I just turned off Enhanced LTE on my Pixel 2 XL and so far I'm getting all messages.  I will also update my case with Google to let them know.  I'm not going to say this fixed it quite yet though until more time passes.  I will keep testing with friends and see.  So far I am getting 100% of texts for MMS (pictures and group replies)

Just a quick update. Google is aware of this issue and have dedicated several of their engineers in resolving this issue. They even reached out to me to use my phone as a test case. I will definitely let them know about the enhanced LTE situation.

@yoolyalana - any update? I want to keep this thread fresh until there is a solution. My frustrations and missing messages has continued.

I am still encountering the issues mentioned here. It's really, incredibly annoying!

As a stopgap, I've started using Textra with the settings set to "Legacy" in lieu of the Messages app. But it's really annoying that I cannot use the app my phone comes with for a very basic function with complete certainty.

Still waiting for AT&T and Google to figure this one out! But I don't know what else to do.

@CHumphries, I'm not really sure. It was something I did based on a post in this thread in the Google Pixel Forum: https://productforums.google.com/forum/?utm_medium=email&utm_source=footer#!msg/phone-by-google/BwyxuNcJj-U/bXRWPpiDBgAJ

Someone there had suggested it as an alternative, though I'm not even sure it's working, because it's nearly IMPOSSIBLE TO TELL.

But anyway, if you want to try it, go to "Settings", then "MMS", and then switch the "MMS Behavior" from "System" to "Legacy".

I"m experiencing the same issue.  Turning off enhanced has helped some, but is not a complete fix.  Good to know I'm not alone.  Hugely frustrating because the phone is otherwise great.  But this going on for a month is almost unforgivable.  

Enhanced LTE is off for me and I'm still losing messages. I had used my 5x for a week and everything was fine. Tried pixel2 again in hopes that it would work. Back to the 5x we go.

@smurfsriot Currently they are tracking my phone as well as several other phones in hopes to find a solution and resolve this issue. They are aware of turning off the LTE enhancement but have noted that this does not solve the issues. Please note that Google is taking this issue seriously and are diligently working to resolve this issues. I am getting multiple e-mails work log (which honestly I do not understand as I am not tech savvy. LoL) But note that they are working on it and also aware of this forum and are tracking the messages. So please keep the updates/complaints coming. Thank you. ~just an employee of Google who is wanting to help

So where is AT&T support on this one? I've been having the same issue on the Pixel XL 2 which started recently. I get "message failed to download" issues for about 90% of group messages. All of my friends, family and colleagues communicate almost exclusively through group messages, so it's been really frustrating. I'v been to the store 3 times, checked APN settings, replaced my sim, and factory reset. Any help?
