Some of my latest PRs, have a failed codecov/project pipe.
Since you guys have skipped these said PRs, should I make any changes to make the pipe pass or you guys assumed that the failed pipe is test related and skipped it because of that?
BTW there is no hint in the review panel as to where the missing coverages are.

Hi Parsa Arvaneh

Thanks for all your amazing work

On my side the pipe coverage failed for the reason that the test coverage decrease of 0,01 %. This is nothing because when we will merged the pr on master the pipe coverage will success

For the moment i don’t review all your PR but try to make my possible to read as soon I can

Thanks again for your support
