Hi Georgii
Thanks for using QandA platform.
The requestedAccessTokenVersion specifies the access token version expected by the resource. Can you confirm if the signInAudience on the application is configured as AzureADandPersonalMicrosoftAccount or PersonalMicrosoftAccount because this is a requirement if the value for this property must be set to 2.
Find documentation: https://learn.microsoft.com/en-us/entra/identity-platform/reference-microsoft-graph-app-manifest
Additionally, please ensure have no more than two key credentials and no more than two password credentials if the signInAudience on the application is configured as AzureADandPersonalMicrosoftAccount or PersonalMicrosoftAccount before updating the requestedAccessTokenVersion property.
You can mark it 'Accept Answer' and 'Upvote' if this helped you
