Check first that the rewards have completely vested.
Some pool farms may have a vesting period after each time rewards are collected, with rewards unlocking at every block. We follow a linear vesting period, meaning that once you collect your rewards, they get vested for a certain number of days. A small amount will be unlocked each day and you can choose to withdraw them bit by bit or wait to withdraw the whole amount all at once after the vesting period is complete.
To check the progress in which your rewards are being unlocked, as well as to withdraw the rewards, you can check the Vesting tab. If your rewards have vested but you are still unable to withdraw them, please contact our Support team.
