Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
I've had the same issue on Windows 7 for a while... also getting frustrated with microsoft "working on it" for over a year. Not sure if this latest update fixed the issue, but here is what fixed it for me. Go to your account settings, check to see if there is an issue and you need to sign again, if not, sign out, then sign back in. After signing in, check for and install the latest update. Doing it in this order fixed the issue for me. Good luck everyone!
