Sure, yes I am rooted. I also use banking apps and Google pay and they work just fine. Using it in the USA.
For the security app I was searching for ways to activating GPU settings, found several guides and none worked, since the flag is already set to True it wasn't a flag issue.
So I download the apk installed through a third party file manager with root access (I use mixplore) it also works with the package installer but some apps wont install unless is with a third party.
I managed to update many of my stocks apps like settings, security, notes etc. Some I have replaced with CN version and they all work fine.
