Device model

No response

Steps to reproduce

1. Have a contact with the nickname different from the name.
2. Create a new message in K9
3. Start typing in "To"
4. If you type the nick name and use the autocomplete/sugestion, the e-mail is in the form of "Nickname" <email@example.com>
5. If you type the name and use the autocomplete/sugestion, the e-mail is in the form of "Firstname Lastname" <email@example.com>

Expected behavior

No matter how I find the contact, the recipient address is always in the same form "Firstname Lastname" <email@example.com>.

Actual behavior

Depending on which field of the contact was matched the name changes.

Hello @cketti .
We have thoroughly tested and replicated the bug scenario, and it has occurred for us on the following device and software configuration:

Phone Model: Samsung A6
Android Version: 10
K9 App Version: 6.702
App Source: F-Droid

This behavior is intentional. I guess people can disagree on whether it's expected behavior. I, too, lean towards making the change and always use the display name.
