I have attempted to add my phone number using the provided verification method, but it seems to be malfunctioning at the moment. As a result, I am unable to successfully link my phone number to my Microsoft account also I would like to claim a Microsoft Reward, but I need to add a phone number. However, I am encountering this problem.
