Hey. Thanks for your reply. I made https://shadowvz96.itch.io/teleport-2bit using SuperTiled2Unity and it works fine on mobile, but I used Unity 2019.2.5f1
I will try to downgrade my project from 2020 to 2019 and I'm pretty sure it should work. Thanks for your response. I'm not really getting an error message, just the .tmx map doesn't display on WebGL mobile. I appreciate your tool! I absolutely love it.
