The product we are building requires immediate contact book sync after sign up.
Right now I have to decide how to display info that the contact book is syncing:
A. Have a small box on app UI which says - Syncing your contacts:
B. Blur the content underneath and show just the info:
It's worth to mention that you can't play around with application while we are doing this.
What would you suggest?
P.S. Examples are very rough sketches
