If your profile is blocked from registering for the PL-900 exam, it is likely due to an issue with your account, such as being blocked by Pearson Vue. This typically happens because of multiple failed payments. To resolve this issue, you should contact Pearson Vue support to get the block lifted. You can find their support link here.
Additionally, ensure that your legal name on your Learn Profile matches your Legal ID, as discrepancies can also cause registration issues.
