iOS login failure

[ynzehettema]

Greetings,

In my testing I'm having trouble getting the SumUp login to work on iOS devices.

Following is a list of steps I take to reproduce this issue:

• I call Sumup.init(key) with an affiliate key that my company maintains (this call returns a successful plugin response)
• I double check the affiliate key matches the one in the SumUp dashboard which has a respective application ID that matches the app bundle ID specified in the Info.plist
• I call Sumup.login() and attempt to login with an account which is registered in the SumUp dashboard. Both the overarching account credentials and the employee credentials produce the same result. -> The SumUp overlay fails with the following message: "Server error. These credentials are incorrect. Please check your username and password and try again" (translated from Dutch as I work for a Dutch company)

This was tested on an iPhone 8 running iOS 16.3. It recently updated to this version so I tried this same flow in iOS simulators with earlier versions. Both iOS 14.5 and 15.5 produce the same output so I can only conclude this is unrelated. The same codepath runs fine on Android devices with the same credentials.

Additional thoughts: The Info.plist contains usage strings for both Location and Bluetooth usage. Me and my co-workers are stumped.

Hi,

I think you've done everything correctly. Have you tried uninstalling and reinstalling the app?

Sometimes it happens to me that I call Sumup.init(key) with the wrong key, then I put the correct one and it gives me the same error when I try to login. Uninstalling and reinstalling the app fixes the issue usually.

After exhaustive testing it appears that I was indeed calling Sumup.init(key) with the wrong key. But curiously only in iOS.

Mea culpa.
