Bests & Worsts Reviews from Amazon

Devie is a newly purchased Amazon Fire Tablet 10 1) When searching for this app, using masterclass, on the Amazon App store, the first hit was for some kind of martial arts videos., Not the MasterClass app that has multiple courses 2) Once I selected the correct app (MasterClass: Learn from the best) by going to the MasterClass.com web site, there was a notification that the app was not compatible with my device. HOW COULD THAT BE?? There were additional instructions about how to download the app by going into settings and doing something like Sync. It was difficult to fine the settings app on the device and 'Sync" had no impact. 3) Now I have to be satisfied by watching the "MasterClass: learn from the best" videos by going to the web site. Not the experience I expected. 4) And don't tell me it is the app vendor's fault. We assume that Amazon vets, tests, approve all apps on the Amazon Apps store.
