General
Known Issue: Model Targets Created with Vuforia Studio 9.11.0 or 9.12.0 Must Be Retrained
If your experience contains a Model Target that was created with Vuforia Studio 9.11.0 or 9.12.0, they will need to be retrained before they can be used.
Advanced Model Targets
Known Issue: Advanced Model Target Retrains After Adding Audio and Select Widgets to 2D Canvas
If an experience contains an Advanced Model Target that has already been trained, and then a user adds a Select widget to the 2D canvas and binds an Audio widget to it, training of the Advanced Model Target may be retriggered.
