Hi @Josh Sp ,
Thanks for reaching out.
I understand you are trying to update the supported account type to "AzureADandPersonalMicrosoftAccount" in your existing application but unable to do so.
The reason for that is if signInAudience is "AzureADandPersonalMicrosoftAccount", then you need to update the accesstokenAcceptedVersion value to 2.
You can update this value in the application manifest.
Thanks,
Shweta
