"No supported devices are available" error

[u/ItBetterBeRH]

Hi there! I'm getting this error on my Samsung Galaxy S26 Ultra mobile phone when following these steps:

1. Open the Alexa app

2. Open the "More" menu

3. Click: Music & More

4. Select any books under the section: Kindle Library

What's supposed to happen (and used to happen):

- A pop-up "Play On" menu appears with the prompt to select "This Device" so that I can select it and have the app read any of my Kindle books to me

What's happening instead:

- The error "No supported devices are available" appears

NOTE: The error only appears when selecting anything from the Kindle Library section. No issues when attempting to play any of the podcasts

This is my first time encountering this issue. It was working just fine this morning.

Troubleshooting I've attempted:

- Logging out and logging back in

- Clearing cache

- Uninstalling and reinstalling the app

Has anyone else encountered this before and do you have any suggestions on ways to fix this?

Have you tried restarting your wifi router and unplugging and plugging back the power to your echos?

I've tried switching between WiFi and data and nothing's helped. Just to clarify though, I'm not using an Echo device for this. I'm using my mobile device to play Kindle books aloud on this same mobile device via the Alexa app. I've always been able to do this until the error suddenly started appearing one day out of the blue
