How can we manage multiple stores with the same email address?

Hi Shopify Community, our app got rejected for the following reason: “Ensure that your app will work on multiple stores if they use the same email address”

We’ve researched this problem and are unsure of how to handle this on the backend. It seems like we have two options:

  1. When they sign on and we know they have multiple stores, they can choose the correct store from a dropdown.

  2. We can become an embedded app, this means that we are able to directly access the store name from the $_SESSION superglobal within the php.

Both of these options would not be the easiest for us. Is there sort of way that we could easily get all the shop IDs for an account?
