Linking to Authenticator app using otpauth://totp url scheme shows an error on iOS RRS feed

  • Linking to Authenticator app using otpauth://totp url scheme shows an error on iOS

    I am linking to the authenticator from a web page using the url scheme that the Microsoft Authenticator App registers in iOS when it is installed - otpauth://totp - I am using this as a convenient way to open the app from my site rather than telling the user to manually open the app.  On the iOS version of the app (unlike the Android version) the error "Secret Key is Invalid" appears.   The error can be dismissed and the user can continue to use the app, but it is a poor user experience, unlike the android version.

    Also, be aware,  that I also use the link format like this - otpauth://totp/B2CDemo%3Aa%40b.c?secret=IU67PONWOM3AITKNT464LLF4YAL4OFUI&issuer=Azure%20AD%20B2C%20Demo  - for the other use case where I want to register a new totp code - this works perfectly fine
