Love this app, but please fix the errors

Im an instructional designer and I love this app. Its very well done and meets multiple learning styles. That being said, Ive come across a number of errors (in the Spanish course) and now Im unable to move forward in both the regular lessons and the lessons to gain more health. This can easily be solved by ensuring more rigorous quality assurance testing before you make the lessons live and/or responding more quickly to reported errors.
