How do I fix the “can’t connect to ...

when I try to open the App Store on my iPad Air 2 all that comes up is a error that says “cant connect to App Store.” I had recently updated to the new iOS 11 beta and ever since then it wasn’t working.

"Beta"?

The official release of iOS 11 occurred on Sept. 19. You should have removed all beta references from your iPad and moved to the official release.
