Hey Champak, There is a possibility that your blog has not been approved by Tripoto. You can write a mail to info@tripoto.com to know the exact reason. Same happened with me last time but I mailed them about the issue and they solved it. Happy blogging!!!!!
I had the same query , so wrote to them. Due to the festive season, the office was closed, so there might u little delay. Don't worry, you will get you credits
