The new version is unusable. The old app/site were a well-functioning reader/storefront, that allowed comparing prices, discovery & browsing, was easy to use with every device. Now the storefront is gone, & the reader is a Kindle. That's comparatively bad for reading & organising texts. It's almost incompatible with mostly graphic content. Amazon - if you want people to use Kindle - improve it. Yanking away thousands of dollars worth of content at will won't gain customers for a bad service.
