If it's about Tasks -- it's all down to CF ( CrowdFlower
) since they're the ones responsible of delivering the Tasks to ClixSense ( and the other PTC sites
) -- if there's none at the moment, just be a bit patient; sometimes CF's known to pop-up Tasks when you don't expect them at all
Then it's "first-come first-click"
Offers on the other hand, depend on the advertiser -- since only they decide where to release/deliver their Offers, all one can do ( again ) is to wait
As for Ads -- regardless of its value -- will always appear; but you have to be currently active ( as in, checking the View Ads section from time to time
) since many ads, regardless of where or location of the member, will just appear without warning
Just a bit more patience and perseverance, sandyfarzana
