Sure, I can take a stab at it. There was a release making some behind-the-scenes adjustments to normal game matchmaking that mistakenly pushed the balance patch out early. It is very unfortunate that it happened twice in a row, I totally agree. As it happened around 1-2am LA time, it required the EU and Southeast Asia teams to wake up and notify the engineers to roll the patch back.
Patch notes are scheduled to come out at a specific time every two weeks. We do this because we support around 20 languages in WR, and don't want to give any specific language early access. Earlier on in WR's development, we got a bunch of feedback that the notes were too early before and ended up confusing players, so we pushed them to be closer to the release timing (around 7pm LA time). Sometimes, articles do slip out early, almost entirely down to human error.
Minor patches (2.4a, 2.4b) tend to come out roughly the same time every two weeks, and the patch notes come shortly beforehand. These patches don't require approvals by Google, Apple and Samsung, as they're just numerical tweaks and occasionally small content or code changes.
Major patches (2.3, 2.4 etc) are a little more fluid, timing wise, but we push the button around 5pm LA time. Ultimately, it's at the behest of the 3rd party platforms to distribute the new build, though - for some it can take up to 2 hours across the world.
So for this one, it sucks, I agree. It's never our intention to push out major changes without communicating them, and it's something I hold our team to a pretty high expectation on.
