Hello! I recently uploaded my portfolio as a game developed in Unity for HTML. On PC it works great but I have a problem that I can't solve when viewing it from a mobile. When I try to restore the game on the mobile, it continues to work, since the cursor and sounds work but the screen appears black and nothing can be seen. I have tried several things that have to do with Unity's Canvas Scaler but I can't find the solution. It would be a great help if someone knows how to solve this! 

Best regards, Andrés Vidal Martín Martín.
