Perhaps you are correct that the problem is not with your Android. (I wanted to know not only the platform of your phone, but also the version of your software. But I understand that you may not know where this information can be seen on your phone.)
But I became interested in your problem and looked for information about your phone on the Internet.
I'll tell you a little about what I found about your phone on the Internet.
First, your phone (as a model) came out with Android 9. At the end of last year, it was equipped with Android 10. As the Internet says, most likely this was the last global update. Those. the manufacturer is not going to update Android. And Android 11 is not included in his plans at all.
Now the manufacturer is updating only MIUI, but this is just the interface, not the core of the phone.
And the security system may be modified somehow (but this is not accurate information).
From all this information, I conclude that your phone's software may not have been updated for 7-8-9 months. And this may be why you are not getting ANYTHING from King events.
But I can be wrong because my conclusions are not drawn from professional knowledge. but on information from the Internet.
