I wish I could give it a higher rating, but it seems with every update it keeps getting more glitches I keep having to contact tech support, for glitching in the lessons more and more have been not marking complete, and its frustrating they should have something for the parent to over ride if the child has done it if the auto fails, its frustating to spend an hour on tech support telling to uninstall and reinstall. I have tried that first and I have it on 3 devices all have issues.
