Introducing cookieless authentication beta with App Bridge

I’m having some issues with app-bridge 2.0.3, specifically the forceRedirect option. My embedded app loads the skeleton unauthenticated as suggested by the Session token tutorial, the skeleton loads app bridge and then app bridge redirects to a broken url at https://<myshopifydomain>/apps/<shopifykey>. Before, it redirected to https://<myshopifydomain>/admin/apps/<shopifykey> and that worked but it no longer seems the case. This affects the flow for creating app subscriptions after confirming the subscription and getting redirected back to the returnUrl, but also I’ve had issues with this during the app submission process.

I created a GitHub issue at https://github.com/Shopify/shopify-app-bridge/issues/65 but haven’t received a response yet. I’m not sure where to go from here or if I’m missing something really obvious.
