Empty your Magicite gauge somewhere close to the beginning maintenance time, because it's 7 hours long!

Magicite becomes full after 16:40 time elapsed. If you can't login until 9 hours, 40 minutes before or after maintenance, you're losing magicite.

If you live outside of the PST-centric downtime, or if you have an atypical sleep cycle, you might want to set an alarm for this. (Thanks to u/Urthop for the idea). Downtime is 11 PM - 6 AM PDT (with DST applied to Pacific time). For filthy easterners like myself, this is more 2 AM to 9 AM.

EDIT the game is back up early! Get in and Git Gud! You'll need to update your app in the store first.
