Huh. The nearest I have to an actual "AOSP" device is my King Kong Cubot phone that has probably the cleanest version of "stock Android" I've ever seen, and I'm going to presume you mean like a Google Pixel / Graphene etc?
Tailscale and the QS tile / notification was solid on that Cubot but to be honest, I've barely turned it on these days and is now one of those drawer phones.
Miui / HyperHyperOS though is a different kettle of fish and exempting Tailscale from its App lel Killer does seem to work. 70-80%ish.....
But there is something that just fuggs up and turn it off/on like most thingys I own π
It's rare to see an April Fools actually work, and the last one I recall that had some up in arms was the infamous Predictable posts are driving me insane

We worked super hard on the above in the background and bravo @Xylight@lemdro.id - you just became GermainZ tier!
