Unable to claim TORN on Goerli

I was testing out tornado cash on Goerli and would like to claim the reward, but I get the below error message saying to wait a few day, but is has been a few days already. Why is this? How to fix it? And is the experience on main net similar?

If you click the link in the warning, you’ll be taken to the page where you can update the withdrawal tree. This is the same on the mainnet.
