Hello FaceUp,
Welcome to the
PhotoDirector forum
Please excuse my ignorance/lack of knowledge of PhotoDirector Mobile. I rarely use it for serious editing, as it's not designed for that purpose. I have it installed on both my iPhone & iPad (not android, obviously), but can find no way of reading tags even when they're embedded in the metadata.
Of course, the PC/Mac versions of PhotoDirector can add & read text tags, face tags etc. I'm not even sure if PhD Mobile has that facility, but I'm happy to be corrected & re-educated.
