Still sending the default Email Text on Account Activation

Have been searching high and low for a solution to this real bugbear of a problem. Deleting the user.mail entries on the database worked as per #4 💬 Still sending the default Email Text on Account Activation Closed: outdated .
In my case I found and deleted the two entries - one each for DE and EN languages. Now any update on the site user account config pages gets saved as a new DE translation (which is what I require for now). However, the default EN mail text remains the same and can't be changed.
Hope this gets fixed in core soon.

Changing to D9.5 as that's where I have encountered this problem.

We had this problem and this is a big issue

We removed user.mail in config table, it works but it's radical, and with a multilanguage website it's really strange after (see screenshot, no more way to translate messages)

Strange that this problem isn't solved after more than a year
