Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello, good day and thanks for your question. I understand that you have installed Microsoft 365 on a different device.
May I check and confirm if you are using the correct account that has the subscription?
Please logout and login again on any Microsoft 365 app (e.g from Word > click on File > Account > Sign out/Sign in or Update License) and see how it goes.
