How can old contacts be deleted from compose/search suggestions? I have checked my address book and these people are not on there. I emailed them exactly once, years ago. Even the emails themselves are gone now.
These people are now permanently in my dropdown suggestions and it is very annoying having to scroll past them every time I start typing letters that match those contacts. I have never saved them as contacts and yet they are somehow stored in memory. Please help clean up my suggested contacts.
