Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello
Are you sure you subscribed to the Microsoft 365 Basic, if that's the case, this plan doesn't come with apps to install. It is only for 100GB of ONeDRive storage.
Can you double check the name of the plan you have renewed?
If it was via Microsoft directly, go to https://account.live.com > subscriptions, see what's listed there.
If it is via Apple, you will need to view it through your Apple account, not Microsoft.
