Change url segment of episerver node in edit mode? Seems like a bad idea to have both on the same...
There is no way to ensure that a router will work before a certain router - it's best practice to make sure that your url is handled by only one router.
You can change your "catalog root starting point" UriSegment to make it unique, more information can be found here: http://vimvq1987.com/2016/03/episerver-commerce-routing-internals-part-2/
Thas anyone knows if it pocible to make Episerver to use Commerce URI instead of CMS URI? If the solution has the same URL like CMS page and Commerce node?
