Review (so you don’t have to read all 30+ pages):
iPhone group chat with a non-iPhone user in the group - missing texts
Doesn’t matter if the non-iPhone user has an older phone or newest, Android, Pixel
Problem is with all carriers
Predominantly iPhone 12, but happening on other iPhones
“Fixes” that do not work:
Reset All Settings (after backup and then restore)
Reset Network
Erase All Settings
Toggle off/on all Message’s settings
Carrier reset local cell towers
Doesn’t matter whether you are on wifi or not
Resetting/ turning on “Integrated Messages” (Verizon only)
Turning on iCloud Messages
Upgrading to iOS 14.2
Swapping out SIM card
Turning off 5G
Some data points to add:
There was a “Preferred Line” option on several contacts during edit. This is a function of having two lines, available via eSIM. I fixed that, chose my cell, thought it fixed… but did not.
I pinned the group chat in question, moved it up to the top of my message stack… and it disappeared. Cool!
Latest problem solve:
Timult (page 29)… not working according to latest posts
Verizon users: downloading Message+ app, doesn’t solve the problem, but lets you know what you missed.
