A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
After live-chatting with a Microsoft rep, I repaired my Office 365 via the programs & features application for PC. My notes and all its functions are restored. If you have a PC, hold down Start/Windows + R, type appwiz.cpl and click "ok". Find Microsoft Office 365 on the list, highlight and click "change" up above, and choose "quick repair" to fix the issue. It will close all your MS Office apps so save beforehand. I restarted my computer to be safe, and now everything is functioning as it should. Hope this helps other people in the same boat.
