Testing app during Play Store release

I am working on releasing a watch face through the Play Store and have set up internal testers. But when a tester tries the link for the release, it only shows that it’s “not compatible with this version”. Watches are paired to the phone so I am not sure what is wrong. I also noticed if you visit the link in a browser it works. I did opt in for Wear OS and have added the required screenshots. Has anyone run into this problem or have advice on how to fix it?

You can publish the watch face immediately. Internal tests are not necessary.
