Votes are no longer using an alt profile so instead you now have the choice of federating your votes or not. Please go to https://piefed.social/user/settings and see the ‘Federate votes’ checkbox. It should be showing the opposite of what you had for the ‘Vote privately’ checkbox that was there before, however the behavior and tradeoffs are really quite different so you might want to revisit that decision.

Whatever you choose there, you can still override that on a case-by-case basis by holding down your mouse button on the voting controls (“long press” on a touch device) of a post/comment.

If this is all news to you, please see https://piefed.social/post/979325 and https://piefed.social/post/956572
