Hey @twstokes !
We will cut the 1.66.0 release on 2021-11-11. I plan to circle back and bump this PR to the next milestone then, but please let me know if you’d rather us work to include this PR in 1.66.0. Thanks!

Hey @fluiddot 👋! Thanks for the ping, I just now added this PR to the milestone and wondered if you could give it a look. The Gutenberg counterpart has been merged. Thank you!

No problem, if the Gutenberg PR is already merged it would be quick to review it 💨 .

Friendly suggestion @twstokes , it's usually best to avoid merging any parts of the PR "domino" (main apps/gb-mobile/Gutenberg PR chain) until all PRs get green and LGTM'd. It's not a guarantee but, that usually helps avoid surprises when a PR ends up needing some more work but the other is already merged. Thanks!

Thanks @hypest, that's true - I had it in my mind that GB Mobile wasn't "complete" until pointed to the GB trunk hash, but that's definitely trickier if things need more work. Will do!
