I have been working on a shopify app which also provides and a theme app extension which can be added to the store. Now what I want is to get the status in my app whether someone has got the extension enabled on their store or not. Is there a proper way provided my shopify to get which stores have got the theme app extension enabled on their websites.
No, there is no way to do so. The best bet is to use asset api to read the data and parse the result yourself. Also, TAE is not relevant to the Bundles topic here. You should post your question elsewhere
