refresh rate problem Oneplus 8 Oxygen OS 13

I wanted to ask is anyone else have problems using high refresh rate on their T- mobile OnePlus 8?

Specifically for me the phone does not allow multiple apps to run at high refresh rate and even makes some apps run at a choppy 60hz, such as Google maps.

And if so, has anyone discovered a fix
