Signup email doesnot update From: name after changing App Name

What I’m trying to do:
Use the signup workflow and the confirmation email mechanism. I am using the standard login workflow from Anvil (if there is an alternative, please let me know). The email sent to confirm signups comes from “appname Accounts”. This does not update after app name change

What I’ve tried and what’s not working:
If you have a temporary app name and do most of the development with that name, for new signups, the From: name during signup email confirmation comes from - “appname Accounts”. If you then change the appname, the email confirmations do not update the app name.

This has happened in a couple of my apps. Kindly check. It would be great if the appname update is reflected in the signup confirmation emails as well.
Thanks

Update:
Found the solution for this. The simple solution is that after changing the name of the app, we remove email from the services list and add it once again. This resets the appname in the signup confirmation email.
Thanks

This still smells like a bug to me.
