As of now gas fees are totally get high at the same time tokens to be transfer is a problem too. Because it has a minimum gas to send tokens to other wallet, as same as ethereum also. However you can't send tokens if you did not follow the minimum amount of gas to send.
I think the main problem why some bounty campaigns that ended cant send the reward tokens because of high gas fee. And some bounty ask thier bounty participants to send eth cover the gas fee to recieve thier reward.
