Pokémon Sleep Maintenance — v3.9.0
Scheduled maintenance for version 3.9.0 runs October 22, 2026, 4:30 a.m. – 9:00 a.m. Below: what the window covers, the sleep-tracking quirk if you update mid-maintenance, and the Halloween / Meal Prep content queued behind it.

Version 3.9.0
Halloween event next
Downtime: Thursday, October 22, 2026 — maintenance begins 4:30 a.m., expected to end 9:00 a.m. (local times shown in the official notice). Times like this are posted in-app under News; the window can slip if work overruns.
Sleep-tracking caveat: updating the app during the maintenance window can interfere with sleep tracking that night. Safer play: start your sleep session from the "Under Maintenance" screen, or wait until maintenance ends and update after your session.

What to do during the window
- Finish any active sleep session before 4:30 a.m. if you can — or accept the interruption.
- Don't force an app update mid-maintenance; it can break tracking for that night.
- After 9:00 a.m., check News for the Halloween event start — Double Candy Research is usually worth planning around.
FAQ
When does the game come back up?
The official window ends 9:00 a.m. October 22. Historically these land on time, but check in-app News if it's still down.
Will I lose my sleep data?
Sessions already recorded are safe. The risk is a session that runs across the update — start tracking from the Under Maintenance screen or wait it out.
What is v3.9.0 adding?
The official notice pairs it with the Halloween event prep, Snackable Nuts ingredient support, the Gengar boost, and recipe-list UI improvements.
