I have been doing code kata problems and doing Python zero to hero certification in GUVI. After every session activity some geek coins are provided. suddenly some of the coins vanish . First I had more than 1000 in my account it became 700 once I go to the reward page, then again I reached to 950 again it became 700 once I go to the reward page. But I have not claimed any rewards. Is there any mistake on my part or is there a bug?
Thank you in advance.
