My HTML5 project loads and runs just fine on the latest versions of Firefox, Edge and Chrome on Windows 10. It runs fine on Firefox on a mac.
BUT, it won't run on Safari 14.0 on a Mac or on either of two iPads. It also won't run on Firefox on an iPad. The loading percentage counter goes up to 100% but then the screen just stays black.
Does anyone know the likely problem? What should I check?
Thanks in advance, Jim
