IPad on iPad OS 15: Messages not syncing or sending SMS (iMessages work)

As of last week I have a new Apple Senior Tech trying to help resolve the issue IM having, still having. The advisor took a series of data for the engineers and emailed me this morning letting me know he has heard back from the engineers and wanted to set a call up to troubleshoot. SO once I get that call, hopefully today, ill report back here with some hopeful troubleshooting news

Same issue for me: on iPadOS 15 (only), only recent iMessages and new classic messages are synchronized. If I delete some message on my iPhone or Mac, notifications stay on my iPad and changes are not synchronized.

Thanks @moki11. Looking forward to your update.

I too went through the process of sharing a plethora of details with a senior advisor so that they could submit a ticket to engineering. Hoping if enough of us report this through to engineering that it will get on their radar. I will let you know when I hear back - hopefully later this week.

I do not have an update on a solution as of yet. When I spoke to the tech advisor a few days ago, he just gathered more information and emailed yesterday to set up another call to gather even more information. IM hoping today I will get a call from the advisor. I will post back as soon as I get any type of resolution. THANK YOU for contacting apple about this. Hopefully they can get a fix.

I know this is probably dated, but...

Same here. When I’m home with my iPhone XSMax iOS 15.0.2 (with super old MacBook late ‘09 running macOS 10.13.6 and 2 older iPad mini’s, i really only use one a mini 2 retina at iOS 12.5.5) they sync fine..i can send and receive both types of messages. But if i leave and come back i have all of the notifications. I had 100+ message notifications (both types) after being gone 15 hours from home. Everything is checked and on except for calls on my iPad or MacBook when my iPhone is near. As all of my devices show in my iCloud under my Apple ID, i know, and already knew, they are under the same account with messages ticked on on every device. I sent an iMessage and a regular text (green and blue) as a test this AM from the iPad in question and my iPhone showed them immediately. I bet when i get home tonight, I’ll have a ton of notifications on my iPad again...it’s just strange to me...as the saying goes, ‘if it ain’t broke, don’t fix it.’ Do y’all think this is yet another way to phase out old devices?? I almost fell out of my chair when this iPad mini had an update to 12.5. LOL

Yep and I still have not heard from the Senior Advisor Ive been working with on this. I actually emailed him earlier as I havent heard from him in 2 weeks. IM baffled at why Apple's Engineers havent found a solution to this yet. Its been months now and an update should of happened to correct it months ago. regardless, as soon as I get some answers, I will be responding here. Please, if anyone is having these issues, please call apple, request to speak to a senior advisor and make the report!

I have the same issue as everyone. I’ve talked to Apple support and a ticket was created for the engineers. Their suggestion was to delete my backup from the cloud and start over. No to that solution. I’ve tried everything else and my iPhone 11 and iPad Pro 2020 don’t synch iMessages or SMS. What a pain to have to manually read and delete messages from both devices. Come on Apple you can do better than that.

I’m having the exact same problem.

Same issue. Still ongoing. It has effectively eliminated group MMS (other than iMessage) from the iPad.

Hello!

Here is the latest update. I spoke with my Senior Advisor today and there is no update on troubleshooting. There is some good news, as more reports have come in about the same problem and now the Engineer team is working to hopefully have a resolution. If you havent called into Apple yet, please do, so they can document and collect logs to help find a resolution. For me, this all started after the 1st major update to IOS.

There is no option for TEXT MESSAGING FORWARDING under Settings/Messages after I unfortunately updated my iPhone to ios 15 today. Nothing syncs. This has been an issue for months, apparently since September 2021 and is STILL a problem as of November 28, 2021. I may erase the phone and go back to the backup before I updated. What a mess!
