I recently launched an embedded app hosted on Heroku and getting this error: "rgd.herokuapp.com redirected you too many times." The app authorizes and runs fine when it is first loaded to a shop. But, when I push a new deploy, any apps that are already installed get this error.
It appears to be something with the way Heroku handles https vs http calls, but I have no idea how to make sense of it. I also set this up on another host (Rever) and got the same error, so it appears to be something with the set up rather than the hosting.
Maybe this is an oAuth issue that it does not properly re-authorize after a deploy is pushed??
I have the redirect URL setup correctly according the the Heroku set up instructions in the Shopify CLI (attached).
