I have an unreleased Android app that I am trying to test using Firebase App Distribution.

I set up a test group with one account, [email protected], and I am logged into the Google account [email protected] on my Android device (a pretty old Galaxy).

I have installed the App Tester app and I can see 21 different builds of my app.

However, whenever I click the Download link, I am redirected to the Play Store, where it says “Item not found” and there is a Try again button (if I press this, I get “Item not found” again).

I also tried clicking the email from Firebase with the link to download the app, but that opens up App Tester, and again the Download button redirects me to the Play Store, which says “Item not found.”

I then made sure the Firebase app to be tested was not installed on the device, and I uninstalled and reinstalled App Tester, and then logged in again. Same problem.

I had previously used this device to install test versions of the app last year successfully, so I’m trying to figure out what has changed in the last few months to break this.

How can I solve this “Item not found” error?
