We have a timer on our bot that only allows it to upvote each users once every 24 hours.
So if there are 2 posts within 24 hours you will only get 1 upvote.
You can get the upvote on the 2nd post though, after the 24 hour period you can "refresh" your post.
Basically just click EDIT, don't change anything and then hit UPDATE. It will ping the bot and the upvote should go through.
OK thanks for the information !👍👍👍
