This is why I want to know from other users if they have Amazon TV that got to work with My Cloud.
A quick digging around on Amazon’s site led me to this page - you may find your answers in the manual (User’s Guide) -> https://www.amazon.com/gp/help/customer/display.html?nodeId=201348270
But I doubt you’ll find someone with My Cloud AND with Fire TV here already…the Fire TV is a brand new product. But the manual may provide the answers you are looking for - on DLNA, etc. I could try to read it for you and find it for you but I won’t…hope you find the answer by some reading.
Before I bought the My Cloud EX2 three months ago, I spent two full days reading the manual - I was interested to learn about it’s capabilities. I never understand why people don’t do more self-initiated research by simply reading a product’s manual, before buying it based on the scant marketing info on a product website. There would be far fewer situations requiring returning a product, although sometimes that may still be inevitable.
