Animated SVG

I'm trying to produce really simple animated svgs for websites.

Snap.svg has been "retracted by the Partner" on the Adobe Extensions site and there are broken links (& tutorials depending on it) all over the web.

The GitHub pages seem confused.

I tried tyburn's svg animation plugin but it failed to export a moving svg, whatever settings I used.

My question is this:

What is the best free (or Adobe) WYSIWYG svg animation editor that you've personal experience of using, available in 2019?

Thanks

PS- I'm obviously getting frustrated that, what I believe should be a simple task catered for by either AI or An, or both, should be missing from those apps!
