Hi, Some times it takes upto 48 hours for the credits to come or if you might have got a mail from Tripoto team saying you didn't earn any points for the trip. Mail Tripoto team in anycase to check.
U will start earn ur credit only when trip is approved by tripoto but u need to breif ur trip details like places to explore, time, days n etc... if u haven't even after that than try to write a feedback in setting to tripoto
