Timeline view in Microsoft Planner

In our organization (same Microsoft 365 tenant), I can see the "Trial active" (or Free Trial) button in the top-right corner of Microsoft Planner, allowing access to premium features (e.g., Timeline view). However, a colleague in the same organization cannot see the trial button at all in their Planner interface, preventing them from activating or requesting the trial.

The trial activation and Timeline button is completely missing for the affected user, even though both accounts belong to the same tenant and share similar roles.

Troubleshooting efforts we have tried the following steps, but the issue persists:

1. Cleared Microsoft Teams cache and restarted the application.
2. Signed out and relogged into the account.
3. Verified that "Self-service purchase and request" is enabled (set to "Allow") in the admin portal.
4. Tested accessing Planner via Microsoft Teams Web version (same outcome—button is missing).

Here is what it looks like for a user with the trial option

vs. one without:

 How can we enable or show the missing 'Trial Active' and 'Timeline' button in the Planner app in Microsoft Teams for the affected user?
