Inconsistent in-app push notification

We're currently integrating Intercom into our Flutter app.

We've set up a workflow that's triggered within a series. The first time around, it works perfectly and the message appears as an in-app notification. However, subsequent triggers result in the message being delivered to the inbox without the in-app notification alert.

This inconsistency is affecting our product onboarding, which relies heavily on these workflows. The experience for our users is crucial and currently compromised due to this issue.

Has anyone else encountered this? We're looking for an urgent fix or any workarounds that could help us ensure a smooth and consistent onboarding experience through Intercom.

Thanks in advance for your help!
