Problem

This morning in the Sentry weekly report I received again tons of unexpected: unknown product for errors (second most "popular" error).
This error disappeared many releases ago, but obviously a significant number of users did not upgrade the app.
That makes the Sentry reports confusing and a bit irrelevant. And all the efforts we put in the code seem a bit useless.

Proposed solution

I know that there are tools in pub.dev in order to nudge users within the app. Can't remember the name of the package though.
For instance, a screenshot about a different app on my old smartphone (Android 21) (not a flutter app btw):
