Unfortunately, we are in the process of removing the Megan Thee Stallion AmazeVR Concert app from all platforms, so we cannot restore function to the app. However, we have released the same concert on the AmazeVR Concerts app, along with several other artists.
If you download the AmazeVR Concerts app (available here) you can access to the Megan Thee Stallion concert on that app instead. The concert is exactly the same, just with an updated menu and more artists to choose from.
If you have previously purchased the Megan Thee Stallion concert, please contact support@amazevr.com for assistance.
