Channel inconsistency: Adaptive Card progress updates work in Teams but not Copilot for M365

Md safin sarker 0

I am experiencing a channel behavior difference between Microsoft Teams and Copilot for Microsoft 365.

In a Copilot Studio Adaptive Dialog, we run a long-running image generation job and poll its status every ~25 seconds using InvokeFlowAction. During each poll, a loading/progress Adaptive Card is sent using SendActivity.

Expected behavior:

Adaptive Cards sent during polling should render incrementally, as they do in Test Chat and Microsoft Teams.

Actual behavior:

In Copilot for Microsoft 365, intermediate loading/progress cards are not rendered incrementally. Instead, all intermediate cards are buffered and only the final Adaptive Card is displayed at the end of the dialog execution.

This prevents showing real-time progress updates for long-running operations in Copilot for Microsoft 365.

Hello @Md safin sarker,
There is a known difference between channels:

Microsoft Teams displays Adaptive Cards incrementally as they are sent.

Copilot for Microsoft 365 holds all cards and shows them only at the end of the dialog.

As a result, real-time progress updates aren't available in Copilot for Microsoft 365. This is a platform limitation rather than an issue with your dialog or cards. For incremental updates, Teams is the recommended channel.

Could you please let us know if you have any further query here.
