So, recently, my sister hasn't been able to vote. I'm not sure why this is happening, it may be that she signs into minecraft with her mojang account, but I'm not sure. If anyone could help that would be great, but if not I have to share my grass with her .
It doesn't. It says she voted, but then when you look back at minecraft the massage say you voted doesn't pop up and she doesn't get anything.
I am going to take a guess that this is .net. It may be a issue with the server itself. Does your sister's mc name have caps in it anywhere? The names are case-sensitive.
I also think te same with the ip thing. You can only vote for a server once, and vote for other servers a certain amount of time on a device (I think) Make sure that she also types her name correctly
