dragonxi An overview of the new dashboard is available at https://help.opalstack.com/article/158/dashboard-overview - we'll have more complete documentation available soon.
Your "site routes" are now called "sites" and are listed in the lower half of the page at https://my.opalstack.com/domains/.
If for some reason you're not able to see the list of sites then please email a screenshot of what you are seeing to support@opalstack.com. Thanks!
