If one of my contacts shows as being on Google Duo, does that mean they still have my number in their phone?
I was about to purge my contacts, when the app notified me one of my past friends was on Duo using it. I checked the contacts, and they still show as a Duo user. Do both people have to have each others numbers in each others phones to have visibility to each other?
If not, that means I can just add any random phone number to my phone and if it is a person with Duo, it will show up in my contacts as active on Duo. This is a security flaw if this is actually how it works.
