Pixhawk 2.4.8 doesn't work well with PX4 11.1?

I flew my s500 quad regularly on Ardupilot, but I wanted to give PX4 a try, so I flashed, configured the hardware, and went flying in stabilized. To my surprise, the left side of the drone’s rotors were not working properly and became very wobbly and unstable in flight. I tried troubleshooting if it was a motor issue, ESC issue, or something wrong with the Pixhawk. I decided to go back to Ardupilot, and everything works fine! Is there an issue with the current PX4 firmware that is incompatible with the Pixhawk 2.4.8? I use Pixhawk 4s at work, so I know they work just fine on the latest firmware, so maybe my old Pixhawk cant run it :frowning:
