Download and installation on Windows 11 went smoothly. Install on iPhone XR iOS 15.5 not working. Installed, went to setting, Buy Pro, Redeem and paste code. With VPN on or off, using cellular data or wifi (same wifi as for Windows, and it worked for Windows redemption with VPN on) – Can’t Connect to upgrade to Pro on iPhone. I’ll try tomorrow, but this is annoying. This is a terrific editor.
