Thanks again for taking the time to help me track this issue.
It seems that the itch.io app is using chrome 87.. (currently the last version is 119)
There is a version of the itch.io app that will come out soon that has an updated version of the in-app browser that would solve the issue (hopefully).
I totally recommend just playing the game in your favorite browser directly.
I'm trying to get in contact with itch.io to push the update of the app as soon as possible, it seems to me that is critical for the app as well.
Thank you, hope you enjoy the game!
