Awesome Table will always be compatible with the last 2 versions of all major browsers. For iOS devices, the last 2 versions are 11 & 12. This means that iOs versions 10 or lower won't be able to load Awesome Table apps.
The issue lies in the fact that the current browser version (e.g. Safari or Chrome) is locked-in or integrated into the iOS mobile device itself. This means that the current iOS version dictates what the latest version of your browser can support. This is completely different to desktop versions (Mac or Windows) where you can independently update the browsers - regardless of OS versions.
Since this issue is device-specific, the only option is to use newer iOS devices.
