Bug Description

Android contact name changes to First Name and Last Name are propagated to Signal Android and then to Signal Desktop. However if a Middle/Last Name on an Android contact is removed the name is not removed from Signal.

Steps to Reproduce

1. Change contact name in Android contacts App. Specifically removing a Lastname or if multiple names in the First Name field removing one.
2. Refresh your Android Signal contact list
3. Use "Import Now" button in Signal-Desktop

Actual Result:

The Middle and/or Last Names fields are not removed from Signal. (If Changing First and Last names these changes work)

Expected Result:

Signal Desktop contact name is the same as that on Android contacts app, all contact names changes are properly synced.

@combat-entropy What versions of both signal desktop and signal android did you last use when syncing? Can you provide debug logs for both?

I have nearly the same issue. If I name a contact on Android as:

Fist name:   Name
Middle name: Middle
Last name:   LastName1 LastName2

I get a contact on desktop as Name Middle LastName2. If instead I set:

Fist name:   Name
Middle name: Middle
Last name:   LastName1

I get a on desktop: Name Middle, the LastName1 dissapears and only fisrt name and middle name are displayed.

I am on Android 13, Signal 6.13.6 and Desktop 6.8.0.

This issue is still happening with 7.5.1

Deleting the Last Name of a contact in the phone's Contacts app syncs properly with Signal-Android, but not with Signal-Desktop.

@pippi1otta sorry about this. We'd appreciate if you could help us gather a bit of information:

1. Could you open Settings window in Signal Desktop, and navigate to the "Chats" tab
2. Press "Import now" button next to "Import contacts", and wait for import to finish
3. Open the conversation with the contact for whom you see the outdated name
4. Press "View > Debug Log", and send me a debug log, please?

Thank you so much!

@indutny-signal here you are - https://debuglogs.org/desktop/7.5.1/865f43f118fca411b4c29a4f64dafbc35277e23077ad0b5b8872b208de331c78.gz

@pippi1otta thank you so much! If this is not too much to ask, could you also provide debug log from your phone?

Caveat: the above log is from right now, but the last time I played with my phonebook was a few days ago. In case you don't find anything relevant, try this one:

(I think I captured it right after encountering this issue. Not sure.)

3. Open the conversation with the contact for whom you see the outdated name ~@indutny-signal

Just to point out, I have multiple contacts with leftover last names. It's reproducible 100%.

@pippi1otta thank you so much! We are looking into it (it might get a fix on Android side)
