Hello Guys!
We have just submitted our second application, only one issue is pending to be resolved.
We have almost run out of ideas, please give me any advice, hint or whatever 
Our application uses the āManaged app installā.
This featureās main functionality is the store owner will see a āgrant accessā page, without interacting with our application directly.
We have set restriction in the distribution settings, to allow shops ONLY with hungarian business addresses.
Eventhough the reviewer could install the application from an UK and indonesian store.
The reviewer also said, we should somehow reproduce this sample ouath error.
My question is how can i get the requested oauth error page, if we go by āManaged app installā?
Since with this solution nothing sends requests into our app directly, is there any other configuration setup what we couldnāt find so far?
Thank you in advance!
Ćkos
P.S.: I have found an issue in the other shopify forum with the same details, but so far nothing usefull has been answered 
What does your current flow look like? When someone installs the app outside of your target country?
Hello Jordan!
The application has not been approved, so only the shopify review team could install it with a UK and indonesia based store.
In the application settings/distribution we have restricted the storeās business country only for hungarian stores.
We go with āManaged app installā, so if somebody wants to install the application, it goes by Shopify only, no any http call our application hits before the āGrant accessā page, only after if they have indeed installed it and accepted the scopes.
The reviewer said we have to somehow produce an oauth error if the store wants to install it outside of our target country, but since we donāt have any active step in this flow by the nature of āManaged app installā, I am really out of ideas how to do that.
They want an oauth error like this:
But with āManaged app installā it should be handled all by shopify.
Any idea?
You can create a development store, and set the country location at a different country and then test it for yourself. 
Hello Jordan,
That would be fine, but based on my latest informations with a development store you can install whatever app you want, these restrictions are not applied for development store.
The other question is still, how can I achive the similiar oauth error by the app install if we goes by the āManaged app installā, as the Shopify reconmends it. Since till that point no http requests have been sent to our app, I am confused how should we achieve this behavior.
