I was forced to upgrade my MacBook Air, and my OS is now Tahoe 26.3.1. I immediately found that the 2021 Office suite I'd purchased no longer works (as the "save" feature was disabled in all software). Directions online said to use the uninstaller tool, which I did, then I rebooted my laptop to attempt to reinstall the software. Now I'm getting a message stating that I've already redeemed the product key. It tells me to log into my Microsoft account to attempt reinstallation from there, but when I do this, there is no prompt or link anywhere to enable a reinstallation. The only thing I see is a promoted subscription to Office 365. Is this whole situation a Microsoft grift, where consumers are now forced to subscribe monthly, despite having shelled out money for the entire suite in the past?
