Dual Launch Zoom with different accounts. (specifically but not limited to Mobile Phone Android and Apple OS)
Issue: You can only be logged into one account at a time. Chats, direct calls, etc are missed from other accounts.
Affected: Everyone who has more than one Zoom account and uses it. 
Solution: Dual Launcher either built in to the Zoom application or adhering to standards of Dual Launchers such as Samsung Dual Messenger.
Alternatives: None. Other than checking manually by switching accounts.
