I double checked the setting, to make sure that it was mobile friendly. I also started the game up on my phone, and everything seems to be in order. I did change the orientation setting, so maybe play again and see if that works. I would re-upload the game itself to see if that changes anything.
However, unfortunately my laptop is once again not working 🙃 So let me know if anything changes, also it could be something to do with your phone model. Although, I have a Samsung 😭 and if it can work on a Samsung, it should be able to work on damn near anything 😂 Also, maybe try clearing out your cookies on your phone, see if that helps.
