Live view not working over cellular data

Hi, I have recently changed phones (Samsung S10 to S21) and since the change i can no longer open the live view feature on any of my Ring devices. Everything works 100% as it should when i am connected to WIFI, so i know that my connections in the house are ok.i have also checked my signal strength on the cellular data and it is more than ok.I have uninstalled and re-downloaded the app, i have tried as many settings as i can find in the ring app and in the phone settings and still arent having any luck.I know/hope that this is going to be a simple setting adjustment, i just dont know which one it is!any help would be very much appriciated.Thanks in advance,Andy
