Device linking performance

[jeffgca]

Device linking over awake seems to take a really long time, regardless of which browser / OS is being used.

What I did:

1. ensure I am connected on browser ( or device/browser ) A
2. open "connect an additional device"
3. scan the qr code or copy over the connection url to the second browser ( or device/browser )
4. wait for magic to happen
5. type in challenge code from browser B into browser A

When it does work, step can 4 take a long time. One potential mitigation is just refreshing the page on browser A, but this is inconsistent.
