I tested out in your bot with a specific date/time for Broadcast and Re-engagement, and both of them worked fine. Here is the screenshot attached.

Due to the high volume of messages being sent at a specific time, it may take between 15 and 30 minutes for your broadcast to reach users, or at times a little more time depending on the scheduled messages.

Could you please add the date/time in both re-engagement and broadcast and let me know if it works in your bot?

So, you set a specific date/time for broadcast and it didn't trigger this episode?

BTW, did the Re-engagement episode work in this bot?

Could you please point me to your bot link at onsequel.com?
