We are aware of the following issue in the game.
Issue DetailsDuring battle with Auto Mode off, Auto Mode may activate when performing an action.
Time AffectedSince the update to version 1.4.0

Because we have found that Auto Switch is involved in this issue, we have temporarily disabled Auto Switch so that it will remain off, even if it is set to on.
We sincerely regret any inconvenience and hope you continue to enjoy Pokémon Masters.
