Sonos Radio not working properly

Hello,

I've had to reset my speaker as radio stations weren't working. I've managed to get the speaker back up and running and it plays some radio stations from tune in and Sonos Radio but It won't play any foreign stations which it did do previously until today. What is the issue with it? Also tune in won't find every country under its locations where as before it did, any ideas why this is?

Manythanks
