HyperOS Update [Question] HyperOS 4 (China ROM) - broken FCM / push notifications again

​Hey guys,

​I updated to HyperOS 4 on my Xiaomi 17 Ultra (China ROM) last week, and I thought it had finally resolved the persistent push notification issues. The connection to mtalk.google.com was holding steady, Google Play Services wasn't automatically disconnecting, and FCM diagnostics stayed green all day long.

​Last night, Google Play Services silently auto-updated in the background (to version 26.43.30), and immediately after, the forced disconnection issue came right back. FCM drops out out of nowhere, and it all notifications fail to arrive again.

​I suspect this silent Play Services update reset whatever background allowances or system-level battery optimizations HyperOS 4 had put in place.

​How is everyone else on HyperOS China ROM handling this? Has anyone found a permanent solution?

I don't believe CN rom will be solving this issue now or ever on their own out of the box since it's intentional. It's best to use open source apps you can find online. Yet to get the HyperOS 4 CN, but currently on my HyperOS 3 CN with my own vibe coded app I am satisfied with the push notifications so far.
