Google Play In-App Review API - Error posting review

Question

I'm using Google Play In-App Review API to display in-app native review window. The window itself opens fine. However once user actually clicks "send review" the window closes with the following error:

Error while retrieving information from server. DF-DFERH-01

This error can be found in other questions, however the solution is always to "clear cache" or other client-side errors. But this error is present for all my users, not just for me.

From ADB:

I'm using Unity 2020.3.2f1. Tried with R8 and custom "com.google.android.*" provided proguard config files, does not work. Turning off all minification does not make a difference, either. I've added Google.Play libraries to link.xml. Build is uploaded and installed though Google Play Internal Testing.

I have no idea what to even try next. Issue on Google Issue Tracker was closed (Won't fix, Infeasible) without further comment.

There's a commonly accepted answer here by HanSoloYolo that isn't client-side related: https://forum.unity.com/threads/google-play-services-not-working.485322/#post-3210077

The instructions likely need updating from the old post, I can see an app signing key certificate in the Play Console in Setup -> App integrity that may be the SHA-1 you need.
