I logged onto Steam, and it downloaded a path. I can now see event rewards prior to choosing a slice. On my mobile account, nothing was downloaded.
Any mobile users get a patch download today yet?
Nothing on iOS yet.
I’ve heard the same about Android. If my shield changes were pushed and everyone else’s weren’t, I’m going to be highly pissed. That would put me at a huge disadvantage.
Nothing on Android either.
After re-reading the Planned Changes to Shield OP, it seems that shield changes are rolling out after R67 (even though they are listed in the updated R67 OP). So I hope that that is true. I can live with that. 
There is an update on the google store.
My bet is that R67 includes the necessary underlying changes to shields - namely the ability for them to push a configurable cooling-off time. They probably hope to have everyone updated to R67 in time for the scheduled roll-out of the cooling-off times; which is a change with a scheduled rollout date rather than a release number.
R67 might not start out as a required update, but I am guessing that will also change on the date shield changes are scheduled to go live.
