Mail: Organise by conversations.
My M1 Mac running 12.3 keeps deferring to 'organise by conversation view', which I detest. I can manually change the option, but it puts itself back again a few days later. My Intel Mac running the same version of OS sticks with my preferred setting of not being 'organised by conversation.'
How do I achieve this behaviour on my M1, please?
iMac 24″, macOS 12.3
