Group MMS messages getting stuck in individual texts instead of downloading automatically in groups

[Android Central Question]

My phone (Samsung galaxy S9+, AT&T) updated to Pie a couple weeks ago and now all of my texts that should be going to group messages are just getting stuck as downloadable MMS from individual contacts. I get notifications that someone has texted me, but then I have to manually download them to get it in the group text. I've checked the settings to ensure that automatic downloads of MMS is selected, but it doesn't make a difference.

This is super frustrating. Anyone have a fix for this?

Make sure your mobile data is turned on.

My wife's S8+ did the same thing and the Pie update somehow turned her data off.

@tube517 It is on. I checked multiple times. Toggled on and off.

Welcome to Android Central! Have you also checked the APN settings to make sure they're still correct for AT&T?
