Error validating application
Or is it due to some glitch in the Facebook server?
How do we contact Facebook team to investigate about this?
BTW Yesterday I discovered if I send a request to /me/accounts with long-term token, list returns with long-term tokens.
I've tested with this: developers.facebook.com/tools/debug/access_token? q= Scenario 5: Page Access Tokens When a user grants an app the manage_pages permission, the app is able to obtain page access tokens for pages that the user administers by querying the [User ID]/accounts Graph API endpoint.
And it doesn't even list the app name in the list of apps (left pane of the dashboard).
When we checked the error_log in the server, the last message is: Why Facebook automatically deleted the app?
When we checked on today, the developer dashboard doesn't show the app.Turns out, the phone was connected to a Wifi network without internet access.As soon as I connected the phone to another wifi with internet, the app installed fine.To use the API, you can issue a Graph API request: time passed to your App along with the access token, your app may only learn that a given token has become invalid is when you attempt to make a request to the API.Also, in response to certain events that are security-related, access tokens may be invalidated before the expected expiration time.
