Prevent user scaling om iPhone/iOS

MDpiano (1.0 MB)I have build this piano that works fine on my mac, but when I test it using Hype reflect, it scales up and down as I double tap the notes. I have unchecked “Allow user scaling” in hype, but it doesn´t help. Any suggestions…?

I solved it. It seems to be okay when I load the piano from a website (I have uploaded it to my ftp-server), but it is still an issue when I preview in Hype reflect.
