It is only an issue on my iPhone 8 with IOS 13, I have no issues when I launch Sportify on my Mac book or the Windows computer at work. My wife has a iPhone 6 and she doesn't have an issue with he Spotify either.
The VPN was causing the issue, I turned it off in Settings/VPN, but it kept coming back on, so I went to Settings/General/VPN and turned it off there.....reloaded the Sportify app and SUCCESS!!! Thanks a bunch.
I have the same issue when I’m trying to use the Spotify. I followed the instruction to offload and install again the Spotify. The same error message is pop up Couldn’t load the page. The iPhone is 11 plus and OSS 13.3
