I am setting up a new phone and already have the App Tester app on my old phone.
On this page Google recommends installing the app in Step 2, but do not provide a link or any instructions for where one might find that app.
All I want is a link to download the App Tester app. I'm familiar with Firebase etc as I have been using it for months for my team's app development.
edit: To clarify, I installed the Tester app on an old device when originally accepting the invitation, per the instructions. But then I got a new device. As far as I can tell, you have a single chance to install the Tester app, which is during accepting the invitation. Since Firebase won't allow repeat email invites, to install the tester app on a new phone I could only think to invite a burner email just to get to the page where Firebase gives you an install link.
I was hoping someone could share the download link for the APK, so I don't need the hacky burner emails to get the app on a device.
Seems they changed it. Now from the official doc:
Step 2: (Optional, recommended) Download Firebase App Tester If you haven't already, download the Firebase App Tester app, which lets you install and access all your test apps in one place. You can download Firebase App Tester from the in-browser prompt that appears after you accept the invite, or by navigating to appdistribution.firebase.google.com on your Android device.
so simply visit appdistribution.firebase.google.com with your device and download the App
