The data couldn't be read because it isn't in the correct format.

I use an app called " Supa Legacy IPTV", and its ran perfectly up until I updated my iPhone 14 ProMax to IOS17. Now every time I try to log in I get this error. The app developers replied that the issue is with IOS17. Can you please tell me what I need to do to get this app working again? My Ipad hasn't been updated yet, and it still runs perfectly, so I don't understand what has changed in the IOS17 update.

iPhone 14 Pro Max, iOS 17

iCloud Private Relay was causing this problem for me.

switched it off, and SupaLegacy works perfect! 😃

settings, click your name, ICloud, Private Relay.

you can switch it off temporarily, or for good.

Hope that helps!

just guess work, maybe they added encryption and the settings of the app you currently have issues with fail to be read because it's not encrypted who knows

why would apple change the way input data is read by an app? There are thousands of reports of the exact same problem with Mojave software when it was released to Mac's. Apple never intended for that problem to occur with Mojave. They noticed there was an issue and rectified it. Kind of feels like the same would happen now? Last time it was an issue with the Automatic Time clock. If its something as simple as that, just tell people how to fix it. Instead of ruining apps for people.
