Last night I had 3 contact names change overnight. One is my own- I had made a small shift to my contact name in signal yesterday and this morning it reverted back to the original.
The other two are interesting. One is how the real name of a user but I had saved their contact in my phone under an alias.

Second is brand new user to Signal -contact in signal was saved as an alias according to user.
Overnight the contact changed to her real name but not how I saved her as a contact. Katherine vs Katie.
It doesn’t make sense?
