Bit of help needed. For some unknown reason the BBC. Sounds app on my A51 will not work using WiFi. It will work no bother using mobile data so the app is fine. The mobile has no other issues using WiFi so my WiFi is fine too. I have uninstalled and reinstalled the BBC sounds app but still only works using mobile data. I checked the app on a S20 and it works no problem using WiFi. I'm stumped.
