Found an error on the site in tasks

Recently I performed a task from chainspot. After pressing the button in the Twitter task , Twitter opens, but you don’t follow, but return to the site and check. During the check, you refresh the page, after updating the task is completed (I followed). If this is not a bug, then accordingly there is such an error in other tasks.
If it’s a bug, it’s only me 0:bb5b2843948cf722a2421134617f128ccccb22ac5887d4bba49da6e2d746d881
You should check or believe, since I don’t know what proof to give.
