Thanks for the excitement!
The servers are now out of maintenance, and the update info is spreading over to your local App Store! We can't say exactly when the update will reach a specific region, as the information can take a varying amount of time to get to your local app store. We sent the update over an hour ago, and in most cases, this will reach other locations within 60 minutes, but can be anything up to 8 hours depending on how Apple/Google feel that day.
If you're using a Google device, deleting your Google Play store cache may speed this up. Otherwise, rest assured the update has already left our base and is on the way to you!
