My Question or Issue

Recently I'm experiencing a strange behaviour with the spotify connect option.

I have a spotify family plan but, as all we know, we can link only one account with Amazon Alexa.

Luckily with the spotify connect option my fiance could use our echo just saying "Alexa Spotify Connect" the echo became available through the wifi within the Spotify app on my fiance iPhone.

In the last two week when we launch the command all my echo and echo dots start searching our devices only through bluetooth.

I tried to reach Amazon to know if they made some changes on Alexa code, but they told me they didn't.

I tried of course to unlink and relink spotify on alexa app and even reset my echo without results.

Can you give me any information about any changes within Spotify?

Thanks for your help.
