How to resolve OAuth issues preventing app reinstallations?

Shopify Apps

Topic summary

App review was rejected because the reviewer couldn’t reinstall the app: after completing OAuth (authorization) the flow redirected to a Shopify page stating “The page you’re looking for can’t be found.”

  • The developer cannot reproduce the issue on development stores, either by visiting the app URL directly or using “Test app on development store” in the Partner Portal. The error appears to occur only when installing from the live Shopify App Store.
  • The developer suspects a redirect/URL handling difference between live App Store installs and dev/test installs but notes they don’t control the App Store page.
  • A screenshot of the 404-style page is central to the report.

Status: No solution or concrete steps shared. A follow-up post only asks whether the issue was ever resolved; the thread remains open/unresolved.

I am submitting my app for review, and got rejected because the reviewer couldn’t perform reinstallation (eg: install and uninstall, or install and perform installation again) successfully.

The reviewer told me my app redirected them to a page like this after OAuth :
(The page you’re looking for can’t be found)

I am scratching my head now as I was unable to replicate this issue , I am able to reinstall my app successfully (via visiting the app URL, or click the “test app on development store” button on partner portal). This error page seems on the live Shopify App Store, which my app shouldn’t have control over!
