Thumb Counter for puzzles

The little thumbs up for a puzzle I thought it would be a counter but if it is 1 and I select it to make it 2 it goes back to zero

Just did another puzzle and it worked puzzle 9307 I’ll keep a record next time of which one it doesn’t work on I can’t remember

Hmm. Maybe it was one you had voted on before? If the button is blue, you’ve already voted for that puzzle and clicking again will un-vote.

Yes I think are correct thanks
