Pokémon Masters EX will undergo scheduled server maintenance on Nov. 8, 2026, from 7 p.m. to 11:59 p.m. PT, during which the mobile game will be unavailable. The developers have warned players to avoid playing immediately before maintenance begins, as game progress may not save properly if the servers go offline while they are playing. The maintenance notice was published Oct. 8, with the game expected to remain inaccessible throughout the scheduled four-hour-and-59-minute window.
