It doesn’t work

Hello,
Putting it simply it just doesn’t work. I’m reading that I’m not the only one experiencing it. There are still bugs that are mentioned in other threads.
So – I created a template, Saved it and… I got a woocommerce email..
I’ve learnt that not only I have to save it, but also enable it… Ok, so I turn on Enable switch and now I can not Save it, because the Save button isn’t active.
So I did what someone mentioned – added a block and deleted this block (it shouldn’t work that way) and Save it… And nothing happened , I still got the old Wocommerce email.
So, for me it just doesn’t work.
