If you want to turn on the camera for Perform Mode afterwards, you can do the following:
Ios
1. Open Settings
2. Scroll down and tap on the MyGroove app
3. Make sure that the "Camera Access" option is set to "Allow"
Android
1. Open the Settings app
2. Tap Apps & Notifications
3. Select the MyGroove app
4. Make sure the camera permission toggle is set to "On"
If you enable this setting, the camera should work fine in Perform Mode. However, keep in mind that the exact steps may differ depending on your device and Android version.
