My Question or Issue

If I ask my Google home mini speakers to play music on Spotify or a specific song or artist, they do. The problem comes when I connect my devices (I've tried with 2 Android phones) and they are not visible from the app to transmit the selected music to Google Home mini speakers. All the devices are connected to the same wifi network and nothing has changed in this architecture. Everything used to work smoothly but now I just can't make it work. When I've asked the GH speakers to play something and they do, just until then, the device appears in the connect section of my Android device (only the device itself, not the group of devices I've created).

I've rebooted the GH mini speakers but no change at all and have my Spotify updated to the last version.
