installation - I can't upgrade from 3.31 to 3.35

[Paul Phillips]

Hi,
I have tried installing the pkg file from here:
https://github.com/get-iplayer/get_iplayer_macos/releases/tag/3.35.0
It completes the install, but when I launch Web PVR is says I'm still
on version 3.31

When I look at the folder where Get_iPlayer is installed the files
date back to 2020. I'd expect to see today's date

I am using an iMac with Apple silicon

Any advice would be appreciated
thanks
