Well this is strange, or maybe not. I recently bought the new Tab S12+ and that why I factory reset my Tab S9+ so my wife could use it. However I used the Tab S9+ to transfer everything over to the New Tab S12+, this was before the factory reset. Now looking at my Tab S12+ I see that the Amazon app is there and works fine. But, and this is the strange thing, if I go into the Google Play store its not there and doesn't even show that it is already installed. Looking at Reddit people are saying the same thing, that google have stopped it being available for the tablet devices. So only way forward is a Link Icon on the from page to the web amazon site.
