I recently downloaded Microsoft Powerpoint on my Mac. I found out that when I edit my presentation it will actually autosave it to cloud, just like the web app. It was working well for a while. But today I closed my window somehow hours of my progress was gone. Turns out that I ran out of the "free 5gb of storage" and I ran out of storage without noticing it, so it did not save. I'm never going for cloud EVER again. We all make mistakes, and this one taught me a lesson not to use cloud storage. BACKUP BACKUP BACKUP GUYS
I'm so used to quick press ctrl+s on my keyboard from 8 years of typing on older versions of office without onedrive that even with autosave, i do it whenever i pause my typing. It's muscle memory at this point, kinda like pressing the space bar after a period.
