There is no reason why you shouldn't be able to pair your Revolve Plus to your Kindle. As long as the Kindle supports one of HFP, A2DP, and AVRCP as Bluetooth profiles. Make sure you are following the steps HERE when pairing your speaker.
When you are trying to pair to the Kindle, does it give you a specific error message at all?
As your speaker is pairing with your Fire TV, the first thing I would recommend doing is restart your Kindle and then attempt the pairing again.
I look forward to hearing back from you.
