Why is iMessage combining two contacts into one thread. I can only text back the last one that messaged me. This started with iOS 12

Never know till you know BUT its pretty clear that it was being addressed as its stated now lets just hope it works! Demo, I would not have seen it till your post.

Good luck. I hope that it works for everybody sharing an ID.

Whatever. I wasn't specific enough. If no one involved in the messaging was sharing an Apple ID it would not have happened. You knew what I meant, and you chose to ignore it. Have a nice day.

Lawrence, you're ignoring that fact that Apple addressed the issue with an UPDATE today. They wouldn't have done that if there wasn't a problem.

Do you realize that what you edited out is the email address to Apple Support? How in the world is that personal information?

the email address that might have been auto blocked is, without the spaces, "**** @ apple com

Seems to be sorted - so thanks Apple! Turned out that it WAS an issue - so glad that I didn't follow the 'fixes' as I would have lost years of chat...

Upgrading all of the devices in my household to iOS 12.1 has fixed the issue.

Well the update to iOS 12.1 fixed the bug.

I am so glad that I did not follow the advice from "high level" people on this forum and delete years of information. The software update to iOS 12.1 has fixed what Apple referred to as an issue.

I concur wholeheartedly!! Thank you Pencil1992 and Apple and to the users who didn't give up!

crickets.
