What iOS version are you on?
Is there a possibility for you to install IF on another Apple device? Just to see if we can rule out your iPad?
Also, have you tried this in another location (with a different internet connection), perhaps at a friends place?
I am on IOS 11 the latest 11.i don’t know
Unfortunately no because I will have to pay for it
Clear cache and I works now thank you for all you help I really appreciated the help and time you wasted on me.
