With approximately 22 million Kindle Fire units sold since 2013, it is time for WD to provide us with an app that works. I purchased the WD MyCloud specifically to allow my family to use their Kindles to access media on demand. The MyCloud seems like a very good product; unfortunately, it is realatively useless for me without an app to connect our Kindle Fires to the MyCloud device. I’ve spent way too much time trying to find a solution. Unfortunately, it seems the only real solution avaialble to date is to return the device and purchase a competitors solution.
Amazon appstore has the application for WD Mycloud.
Below is the web links for the app. I hope this helps u before u plan to return.
