Why Do Users Receive Both Versions of A/B Split Campaigns in a Flow?

Problem

Users are receiving both versions of A/B split campaigns in a Flow.

Explanation

• Users who enter and exit a flow multiple times will receive all eligible versions of the split until the flow stops.
• However, an issue arises when two identical versions of the split are active without delay between campaigns.
• In this situation, if both versions of the split have the same trigger condition, users are expected to enter and exit both versions of the split.
• Since the campaigns are evenly split (50:50), users have a random chance of receiving either campaign each time they enter the flow.

Solution

Avoid using identical flows or the Maximum times to show message ever feature. These restrict the campaign from being shown a maximum number of times as defined during campaign creation.
