OnePlus is terrible with updates!

Mostly a rant I suppose...

For months, I dealt with a lot of small issues on my OP11 that I found to be very annoying. I had contacted OP, and they told me to do a factory reset. I really did not want to do that, as I also use my phone for work. Well I finally did the factory reset at the end of November, and all the little issues went away.
I just got the OOS15 update, and ALL THE LITTLE ISSUES ARE BACK!

WTF OP? I shouldn't have to factory reset my phone every time you push an update!

Once again, I can't open YouTube music from Android auto. No, I have to unlock my phone, so it can open up in AA.

For reasons I don't understand, my display turns on whenever it feels like it to show me the clock, even though the phone hasn't been touched. I notice this in my car (again running AA), because of where it sits. The clock just randomly will light up.

That's just 2 examples I have from my drive in to work this morning. It didn't do either of these things before the OOS 15 update. I didn't change any settings on my phone. Why is it I cannot get an update that doesn't mess things up on my phone?
