Suggestion

I maintain the Ungoogled Chromium flatpak and recently renamed the App ID from com.github.Eloston.UngoogledChromium to io.github.ungoogled_software.ungoogled_chromium.

Users got confused by the prompt and thought that the change was malicious, or that they'd lose their browser data if they accepted the prompt to migrate to the new app ID, etc.

I think that the main issue is that terms like "end-of-life" should not be used when informing users that the package has been migrated over to another app ID. Also, the prompt should be MUCH more verbose explaining in detail what (or at least that) app data will be migrated, and contain some wording that reassures users.

Here are a few examples of confused users:

An alternative solution would be to get rid of the prompt all together, I don't see why any user would say "no" to this in the first place.
