Here's what this feature does ...

Unique to On-Pace GPS – sending automatic “Pick Up the Pace” (PUP) messages to slow groups – this feature is designed not to harass players. It’s smart enough not to send a message if there there is no room in front. Politely asks players to close the gap only if it exists. You control the pace threshold and other variables. AutoPUP can be toggled on and off and there is a Do-Not-Disturb feature for individual carts.
