Hey @Farhaty,


We've received a few reports of this recently, in most cases the issue is being caused by an improper redirect to the Shopify oAuth link. Please see this doc for more information. If you're seeing the same issue in Safari, this is most likely the issue.


Once you ensure that your app escapes the iframe before redirecting to Oauth, you won't see the issue anymore. If you're still having trouble with it, please share the code you use for the authentication flow.
