App incompatible with iOS16.3 and prior

help
1

Hi there.
I have discovered that my MeteorJS v3.1 web app is incompatible with mobile browsers running iOS16.3 or prior.
Just a blank sceen appears on these browsers.
I believe it could be because of KaplayJS integrated into my app.
What would be an elegant way of handling this for these browsers?
Can I pickup the iOS version and display a message i.e “Please use device iOS16.4 or higher”?

When you debug your device with Safari on a Mac, do you get any error in your console?
