Isolate the Issue and Gather Tenant Information
Determine the scope of the error to identify if it is a localized browser issue or a broader tenant-wide problem that requires Microsoft Support.
Because this error can be triggered by account permission glitches or backend syncing issues, it is important to narrow down the cause by testing different variables before escalating the issue.
Try adding the plan to a completely different portfolio to check if the 'Could not select plan' error is isolated to just one specific portfolio.
Ask another user in your organization with appropriate permissions to attempt adding the same plan. This helps determine if the issue is tied specifically to your account.
Log in to Planner Premium using a different web browser or open an incognito/private window to rule out browser cache issues or extension conflicts.
Collect your tenant details, plan type, browser version, and take a screenshot of the error message. Contact Microsoft Support and provide these details so the issue can be properly investigated.

Frequently Asked Questions
Why does Planner Premium say 'Could not select plan'?
This error typically occurs due to backend syncing delays within the Microsoft 365 tenant, local browser cache conflicts, or insufficient account permissions to modify the target portfolio.
How do I know if this Planner error affects all users?
You can determine the scope by asking a colleague with similar permissions to perform the exact same action. If they succeed, the issue is likely isolated to your specific account or browser.
Where can I find my tenant details for Microsoft Support?
Tenant details can be found in the Microsoft 365 Admin Center under the Organization settings. If you do not have admin access, you will need to contact your IT administrator to retrieve your tenant ID.
