Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello Pavio Muniz,
Thank you for posting on Microsoft Q&A forum
I can see that you have sign up for the Microsoft M365 LinkedIn Premium 12-month offer, but you haven't received your LinkedIn premium subscription yet.
Is the reason you haven't got LinkedIn premium because the activation hasn't been sent to your email?
If yes, then please wait for at least 24h before checking your email again, it can take up to 7 days for the email to get to you. After that amount of time, make sure you look for the activation mail in the spam section too.
If you need further assistance, feel free reply back to this post. I'll be happy to help.
