Hi, there seems to be a long-standing bug with the 2FA for Connections.
I've added two iOS devices (a tablet and a phone) to the approval device list. However, approval requests only go to one of the device (the device on the top of the list).
The documentation section titled "Multiple approval devices" stated "All approval devices in the list will receive a push notification." This is not working, please fix it. Thank you!
