There are many times i forget to vote even if i set an alarm. I can usually keep it within 10 mins of each vote, but there are times i go hours w/o voting thus ruining my chances to vote. Also if One wanted to reset the timer to a better time they'd have to wait a day to do so. What i recommend is that the Vote links reset at the time the server date changes ex. 9-30-18 -> 10-01-18 that way we could vote "each day" without having to wait on a 24 hr timer if at all possible.
If I understand this correctly I don't believe this is something that Harmony has control over.
Each voting website determines how it handles votes -- IE allowing you to vote once every exactly 24 hours or immediately again once the day rolls over. From what I've noticed most sites typically opt for the former and Harmony doesn't have a say in it unless we were to change the voting sites to sites that opted for the latter.
