Kirby Uniform 4 email templates — can’t get to work @mzur

Going round and round trying to get Uniform 4 (Kirby 3) email templates happening in the standard way.

I have it working using session storage, which is a relief. But outside of that, the form fails at the point that it meets the 'template' => 'my-template' code.

Despite puzzling over the Docs, I think I need more of a step by step. I just can’t work it out. I’d love to get it working without session storage. (I can make no sense of how it relates to the latest Kirby form code.)
