Play Store pre-launch performance issues?

Hello everyone,

I have uploaded a small game demo to Play Store which is under review currently, but I got some warnings about performance issues. It says the frames were slow on Galaxy S9, however, I tested my game on much older phones and the game always brought stable 60 FPS, even on a Galaxy S6, so I find it hard to believe that it has issues on a much faster phone.
Should I be concerned about this warning, or can I just ignore them if my own testing shows good results?
