Customise Link Not Working

Shopify Partner

Hey all,

A quick one, so when you're viewing a collection page whilst logged into your store, you have an 'Edit Collection' and a 'Customise' button. However, the 'Customise' button is not going to the correct URL and is instead taking you the theme customise screen with the homepage showing - not the collection you clicked on.

Because of this there isn't a way to navigate to a template that isn't linked in your menu/on a page to customise it - unless you edit the URL.

Can this bug be looked at? Our app is dependent on this link working.
