I have a cloud Target database. For some targets (not all), upon successfully recognized, the Trackable.getUserData() returns string of "false" instead of the metadata I uploaded for those particular targets. In the Vuforia portal, I have verified those metadata have been properly uploaded as I can download them and view. For all the other targets, the Trackable.getUserData() returns the properly associated metadata.
This particular issue occurs to Android, iOS, and Web api for those image targets.
Has anybody ever experienced similar problem? If so, could you shed some lights on how to address this?
