I found that "Phone.KeyChainPut()", which was working precisely in the previous version of iOS, has stopped working in iOS 26.1
Does anyone know why? And what is the solution?
As I found, if you save the value with iOS before 26.2, it will be restored with 26.2. The problem occurs when you save with iOS 26.2
In other words, Phone.KeyChainGet() works properly, while Phone.KeyChainPut() does not.
