I know this is great and groundbreaking seemingly. And that it was and more was already there in Telegram, for years.
This is just unfortunate if it has been implemented like Telegram and it seems it has.
I should be able to dictate that “if I initiated communication” to “username” or “from my username” my phone number should not be linked to it even though the other person has my phone number in their address book saved, because that doesn’t mean they are a friend or even if they are I might not want to know that or chat outside the username.
I will try to access the beta (pretty sure it’d be full by now) and test how it goes but I hope it has not been implemented like Telegram after taking all these years.
Though I like that they have essentially nuked vanity username rush and grab in the bud. Kudos.
