Cannot access to Office Insider

[shyleyn chothe]

Hi, I recently bought and installed office 365 because I was mainly attracted to its excel's new formulas and dynamic arrays. However, I could find ways to access office insider as it is the means to use those formulas. And my office 365's account section does not show 'office insider' option at all. I use windows 10 pro. I had installed ms office 365 mainly to get access to those excel formulas.
