Hi Microsoft community,
I have come across some odd occurrences lately - we have an app linked with SSO to our organization. User's typically use the SMS option to MFA in to the app. However, recently for a few users, the OTP has been sent via WhatsApp (using the account "Global OTP Services") instead of the usual SMS.
We have made no changes in our org. to allow for this.
Does anyone know what is possibly going on? I cannot seem to find where that would even be set, or if there was a Microsoft announcement.
