Don't panic! Why missing out on FCU is NOT a big deal...
(All About Windows Phone)

Don`t obsess over missing out on Fall Creators Update (FCU), you`re not missing much - on Mobile, at least. I write this for all the Lumia 640, 735, 830, 930/1520 owners who have been following along at home with AAWP, accessing all the various official production and Insider-level updates. You`ll have ended up on Creators Update, but don`t lose sleep that you`re not on FCU, you`re not missing anything important. Really.
