I have not used BBC iPlayer  since January this year but went to use it over Easter and found the app not functioning and looking at all Sony installed apps it seems to have been removed. Any suggestions on how to reinstall?

Looking at firmware updates for the model it lists one in February 2021 as v3.006 but I have this already installed since 25/10/2019 as PKG3.006eua. Is this the same or has been been wrongly numbered?

Any one else had this problem? 

I downloaded the update onto a memory stick but the TV does not recognise the USB on the screen.
