Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
I understand how frustrating it can be when you’re trying to resolve a billing issue but keep getting redirected through automated support.
If you have access to a Microsoft 365 Global Administrator account, you can create a support request through the Microsoft 365 admin center by following these steps:
1.Sign in to the Microsoft 365 admin center using your Microsoft 365 Business administrator account.
2.Select the Help & support (headset) icon.
3.If Support Assistant is enabled, turn it off.
4.Type contact support in the search box.
5.Select Contact support, then choose Phone or Email to submit your request.
Once the request has been submitted, Microsoft Support will contact you using the method you selected.
Regarding Mac compatibility, based on my research, Planner and Project Plan 3 includes the Project Online Desktop Client. However, the Project desktop application is not available for macOS and requires Windows. On a Mac, you can still access the web-based Project features through a browser.
For more information, you can refer to this thread, which specifically discusses the compatibility of Project Plan 3 with macOS.
I hope this information helps.
