Can't unstake kava coin

I can’t unstske KAVA after 21 days. What is reson?


Kava adress, which i used for delegation coin: kava1tzsn4jg0tn3xnps7kd87n7r2xc3ndaq6w996p5

The issue is due to no available KAVA to pay for the fees.

But kava only delegation. I click «unstake» but kava delegation to stake

I checked the address and you have already undelegate successfully. Do you still have issues?

No, i havn’t issuse. I just update trust wallet and undelegate successfully. Thank for help.
