i currently have Sonos bridge, Sonos Play1 and Play3 speakers and using Android app on my phone to control the system.
All was working fine until recently when my both Play speakers disappeared and i can’t add product in the App as it’s all grey.

So, you likely have a mobile device that doesn’t have a supported OS on it. See the supported OS FAQ. This likely means you’ll either need to update the OS on your device, update the speakers to match the Sonos app you’re running, or borrow a mobile device from a friend to add a new device. Once you’ve added it, your “old” controller should be able to play music for you.
