I've received this e-mail from facebook:
Souts Pay has been making recent API calls to Graph API v2.0, which will reach the end of the 2-year deprecation window on Monday, August 8, 2016. Please migrate all calls to v2.1 or higher in order to avoid potential broken experiences.
We recommend using our new Graph API Upgrade Tool to see which of your calls are affected by this change as well as any replacement calls in newer versions. You can also use our changelog to see the full list of changes.
But when I click at Graph API Upgrade Tool I got this message:
Your app hasn't made enough calls to the Graph API to show any info, or there are no changes for the methods you selected between v2.5 and v2.6
So should I worry about this facebook issue? If yes, how can I make this upgrade?
