Hi @AlexaHogg71
Welcome to the Sonos Community!
I’m sorry to hear of the issues you’re having with BBC Sounds on your Sonos system - I presume it was working without issue before?
I was unable to replicate the issue you’re reporting with adding BBC Sounds to my own system - I was able to add BBC Sounds without trouble.
Please try rebooting your phone/tablet and/or try from a different device, if you have that option.
I also recommend that you reboot your router by switching it off for at least 30 seconds and trying again once WiFi has returned.
If you continue to have problems after performing these steps, I recommend you get in touch with our technical support team who have tools at their disposal that will allow them to give you advice specific to your Sonos system and what it reports.
I hope this helps.
