Web Link point tally seems to be broken?

I know for a fact it's not 0, I already did all of my event tasks and I doubt I'm the only one.

Can someone who works in game/web development please tell me how hard it would have been for them to program an API for that? Because I doubt it would have been that difficult to do... I mean maybe the inclusion of both releases of the game muddies things up, I get that but I still doubt it's that big of an obstacle....
