Right now, your primary email address serves as the default account on all other Proton Apps. E.g., If my primary Proton email address is robert.mckoo@pm.me, this will also be the the default user for Proton Drive.

Just because I have a primary email address I want to use to communicate externally, I do not want to have this email address associated with anything else.

It would be good if primary email address in Proton Mail would just be that while account management / user profile / identities remain separate from any of this.

Thanks!
