Wix OAuth App Installation Failing on Mobile – Redirecting to 404

Hello everyone,

I am developing a Wix app using React Native Expo, @wix/sdk and custom legacy and facing an issue with the OAuth installation flow. When trying to install the app:

  1. The install app URL does not work when accessed from a mobile browser (it only works on desktop).
  2. After switching to “Desktop Site View” on mobile and proceeding with the “ADD APP” step, it redirects to:
https://www.wix.com/installer/undefined

which results in a 404 Page Not Found error.

I have already:
:white_check_mark: Set the Redirect URL correctly in the Wix Developer Dashboard.
:white_check_mark: Verified that the Client ID is correct.
:white_check_mark: Ensured the installation process works on desktop but fails on mobile.

Has anyone faced a similar issue? Could this be related to Wix’s mobile installation process, or is there something I might be missing in the OAuth setup?

Any insights or solutions would be greatly appreciated! :raised_hands:

Thanks in advance! :rocket:
