Newbie - Can't get Radiomaster TX12 to bind with SFHSS RX

Hi all, hopefully someone can point me in the right direction!

Never done RC, during lockdown decided to take up building model planes. Made a few balsa and tissue free flight then decided to go down the RC route and bought a Radiomaster TX12 and a kit which had a SFHSS RX. Couldn't get the two to bind, bought a Frsky D8 as an alternative which paired immediately (so I know that the TX is fine). Thought I had a dodgy SFHSS RX so bought another one - and can't get this one to bind either (it's a Microzone E6-A).

Any ideas what I'm doing wrong? Followed all instructions, tried different frequencies etc. no joy...

I am not sure but according to github Radiomaster TX12S it does not work with S-SFHSS not sure since the last time Github has been updated but they do not list it. I am sure someone will be along to verify if it can or not and how.
