We redirect users to the theme editor via a deep link to enable the embed app. The problem is the deep link has stopped working, and the error occurs “App embed does not exist”.
I double checked if the generated link is correct, and it seems all is fine:
I have the exact same problem and I have not been able to fix it - before I fugure out how to do it I just let the deep link go to the app embed section and leave out the activateAppId part. But that is not a good solution…
Shopify definitely hasn’t resolved the issue yet, at least not in my case. I think this problem has to do with the default language setting of the store. If its ‘English’, it’s no problem, but if its another language, ‘Japanese’ for example, the deep links do not work and it gives this error or the ‘xyz’ block could not be added error.
