My OnePlus 9 Pro Isn't Receiving Updates—Software Stuck

I'm frustrated because my OnePlus 9 Pro isn't getting software updates anymore! The device is permanently stuck on an old version, even though it's supposed to receive regular updates. I've tried everything possible—checking manually, restarting, and reaching out for support—but nothing has helped. The phone continues to say there's no available update, even though newer versions are clearly out there. What’s the point of buying a premium device if OnePlus can't keep it properly updated? This is completely unacceptable for a flagship smartphone! I demand that OnePlus immediately resolves this issue by enabling updates for my phone or explaining why this problem is occurring. OnePlus, stop ignoring customer complaints—fix this software issue now or offer another effective solution!
