How do you get them back?
For me they were just available again. No further action needed.
Thanks, currently shows 4 but time may add to that.
Click on the vote-counter (top-left of page) - and, if one of the counted votes was yours, then you’ll be offered the option to remove it (for use elsewhere).
Not doing that for this closed one!
My vote is locked at
Clicking on the Closed vote (shows just my vote) I get a fly out with me on it Click on that and I end up in my activity with no sign of any votes.
