Hmm... it's working for me. Did you log in? (Bottom left corner of this page: https://alpha.leofinance.io/threads/view/bcpoets.threads/re-leothreads-pk5h5gv4) After you vote it will ask you to confirm the transaction. I use Keychain so I have to approve with that. Then it will show some text about json something loading. After that it will vote.
@anomadsoul maybe you can help out? @driptorchpress also seems to be having issues.
