I've been having an issue since iOS 17 & macOS Sonoma came out where messages in iCloud inflated by 3x, from ~1GB to 3GB+ in mere weeks. It kept inflating when I did nothing but delete things. Like I mentioned in the linked thread, I tried calling AppleCare but ended up with nothing. The senior advisor just kept telling me it was my fault that my messages suddenly and rapidly inflated despite the fact that I had done nothing but deleting attachments and conversations, including anything new to confirm something was broken. I got lucky and was able to jump on a family member's 200GB plan when I ran out of storage, and it inflated by another gig since. I figured something was obviously wrong and that they'd fix it soon.
But now after updating to macOS Sonoma 14.2 I have stuck processes related to syncing messages. I've tried restarting my Mac and force quitting these processes, but they re-appear when messages tries to sync again and it gets stuck in a loop where there's a bar in Messages.app saying "Synchronizing with iCloud" that never moves. The exact same thing happened before on my iPad, and now on my iPhone every single time I open Messages since 17.1.1 released. I also had an issue where after updating to iPadOS 17.1.1 & .1.2 the area above the SoC got really hot and battery drained like never before in the half decade I've had my iPad, until I restarted it. And I realized now it's probably related to this... Something being broken server-side is one thing, but now it's seemingly affecting my devices directly where these infinite processes eats CPU and battery.
I have a few messages in various conversations from the past few years I'd rather not lose by nuking everything, not even being a guaranteed fix. I've spent so much time trying to troubleshoot and fix this, but it just keeps getting worse... I don't know what to do at this point, I'll try giving AppleCare another chance but any help is very much appreciated!
TL;DR: I suspect something broke with messages in my iCloud account right after iOS 17 & macOS 14 released. And now these backend issues seem to negatively affect all my devices without me knowing how to fix this myself without any data loss.
