I downloaded version 5 because version 6 has lost a lot of features. But then, I wanted to go back to version 4... And it was the best thing I ever did. :)
Version 4 has everything you need. I'm surprised at how little Microsoft has added, and with version 6 it really sucks. 🤮
In version 4, you have Notes, Tasks, News, People, everything.
Even in version 4 you can still use Cortana to create tasks. I highly recommend using it again. :)
