"Oauth error invalid_request" when trying to access Govalo
Shopify sometimes requires merchants to re-authenticate on some apps, which can cause the app to be inaccessible for some users and the error Oauth error invalid_request to be displayed:
This is usually resolved by having the store owner access the app, so Shopify will automatically prompt them for the re-auth. In the event that the store owner is unavailable, you may try to resolve this by accessing the following URL, after which other staff in your store should be able to access the Govalo app again:
Make sure to replace "MYSHOPIFY_URL" by your store's myshopify URL, as in "https://govalo-site.myshopify.com/admin/apps/govalo/auth".
