Hi, I received the same message, but when I went to the tool
developers.facebook.com/tools/api_versioning/839366496155498/
it says Upgrade from: 2.0 Upgrade to: v2.6
and there is 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 v2.0 and v2.6
In any case I can't find a way to confirm the update, there is no buttons or something to confirm the upgrade.
Today I installed the jfbconnect_v7.0.2.
I also hope for a your suggestion.
By the way, I'm very happy about the new auto-posting tool, I will study and use it.
Best regards
Francesco
