you should increase delegation to a feasible amount, or undelegate.

delegation of 1sp results in vote weight less than 0.01%, so upvoting is not possible(everything is automated)

If I add extra 3sp will it do?

for now, i think if you delegate 4sp you'll be able to get upvote. but note that if @jsup's total sp increases, your vote weight might become less than 0.01%.

how to undelagte please share the link and support

Please note that the minimum possible vote weight is 0.01% and @jsup's SP is over 870kSP. You should delegate more than 90sp to safely get upvote.

i dont understand this weight thingy
