Dated and unusable App Development Course

In April I bought an App Development course. It took me a while to download the necessary programs etc but as soon as i got started it was clear that the program being used (App Inventor 2) and the one that the course was training on (App Inventor 1) were VERY different. To add insult to injury, App Inventor 2 was launched in DEC 2014, and is no longer available or supported. I battled through the first modules, using google, but it got to the stage where the differences are so great it is impossible to continue. Frankly, I find it dishonest that a course was sold for a product that had been upgraded MONTHS before and was no longer supported on the design website.
