Internal app sharing show downloading error | Error retrieving information from server. DF-DFERH-01

Question

I published my app in internal app sharing. After I shared link to download to myself, but to another account. I turn on internal app sharing in Google Play on my phone. When I click downloading, I catch error -> Error retrieving information from server. DF-DFERH-01

I tried to test in two phones, but with same google account.

Answer 1

There is a step I missed - testers have to opt in to the test program before they can use the shared link, and until they do they get the opaque DF-DFERH-01 error. On the Play Console under Release Management, select App releases. In Internal test track, click Manage. Under Manage Testers click the drop arrow. This opens up a panel, and near the bottom is an opt-in URL. Copy this and send it to testers. They have to click on this link and agree to opt in to the test program. They can then download the current version. After this they can also use internal app sharing links for new builds.
