MuSo BBC Radio not live

Hi, it has happened a couple of times now and since it just happened again I thought it worth asking if anyone else was getting the same issue.
Basically just turned on the MuSo to a preset for BBC R2 and it was still playing the Rylan show even though it was 18:25, changed radio stations, went back and Lisa Tarbuck was on.
Any ideas on what is going on ?
