What happens when users are stopped from entering a Canvas?

When users are stopped from entering a Canvas, they effectively exit the user journey that would have taken place within that specific Canvas. This situation implies that the intended engagement experience was disrupted, meaning these users will not experience the messages or flows that were planned for them. The Canvas serves as a structured path for user interactions, so halting their entry means they are removed from that intended interaction sequence entirely.

This context underscores the critical nature of user journeys in engagement strategies and how interruptions can lead to potential disengagement from the overall marketing efforts. Other options do not accurately capture the consequence of stopping users from entering the Canvas; for instance, while no new messages may be sent and previously queued messages could be affected, the primary and most immediate outcome is that users exit the journey altogether. Similarly, notifications may occur under different circumstances but aren't inherently related in this context to the stopping of entries.
