I keep losing some of my contacts from my Contacts App. It seems that when I find one I lost, it's an older one. What's happening and can I retrieve these lost contacts? Keep in mind that I only find out that I've lost a contact when I go to look them up (call them). For all I know, I could have lost a ton of contacts and never know it until I try to look them up. I'm using Android 11. This also happened on my last phone so this isn't something new!
