Answer:If you are unable to click the claim button on ygov.finance v2, it is likely because this staking has been deprecated for over a year. You may want to try claiming your rewards via the smart contract associated with the website. To do this, you will need to have a compatible wallet that supports the smart contract, such as MetaMask or Trust Wallet. Once you have a compatible wallet, you can follow the instructions provided on the website to access the smart contract and claim your rewards. Be sure to double-check all information before submitting any transactions, as mistakes can be costly.
