I'm using the extension: 'Featured Product' and have edited the template (using theme development tools) to add a couple of extra classes on theme:local. After theme:deploy and activation I don't see any of my updates. I've tried to access with extension development tools and it won't download My question is how do I deploy extensions I've adapted locally or is it even possible?

After making changes to your theme template files and deploying them, you then need to activate them.

They're already activated Steve, but have just reactivated. Still not showing changes. Just in case it makes a difference - the extension is the NetSuite 'Featured Product' extension.

And have you visited your site with a clean browsing cache (ie emptying the cache or using a private browsing session?)

Yeah - tried both.

?

The files I've amended locally is here > workspace > extensions > suitecommerce > FeaturedProduct > Templates >

That doesn't seem correct

Yeah - now I see what you've posted - I know it's not (although it works locally)

I would advise you to follow our documentation on this https://developers.suitecommerce.com/section1498666438

Yeah - I'm reading through that now.
