Exact same issues on my old leather MagSafe wallet, so I brought a new one from the Apple Store ‘blackberry’ colour. Yep that’s a word we don’t hear often in tech anymore. Anyway, I’ve reported it in all versions of iOS 18.1 when in beta and they still exist in iOS 18.2 beta 1. I’ve removed them, restarted phone to no avail unfortunately.
I am unable to add my Apple MagSafe Wallet to my iPhone
I recommend that you take this issue to the Apple Support Community. https://discussions.apple.com/
The Developer Forums are for questions about development on Apple platforms, and this question does not seem to be a development-level issue.
