So the issue I have been having is with the partner site gtop100. Every time I try to vote I get to the stage that sends me to their page. After I complete the captcha verification and try to vote it says I have already voted and that I have to wait till midnight. I always vote from my phone and I have tried both on wifi and 4G on both the normal browser and with the desktop version on. I haven't been able to vote for the past few days because of this and it has happened to me a handful of other times before. But when it was happening before I would just have to wait until the next day and it would start working again.
I've had the same issue as you before, you can read more on my thread here https://royals.ms/forum/threads/voted-no-nx-again-uu.112320/#post-628616 where Andreas was workng on it. Even though gtop says you already voted on your phone, if you try it on desktop it should work. The problem is with the phone itself. After few days voting on desktop only the problem fixed itself
On the phone there was a issue about Java Script, it could only work with Firefox, and now even with it, doesn't work. Now for saying you already voted, maybe you're using a vpn? You know it doesn't reset at midnight, right? It counts exactly 24 hours after your last vote (i.e if you vote at 9:15 a.m. you only can vote again after 9:15 a.m. in the next day) If any of these ain't your cause, then I have no idea ):
The switching to pc once fixed it. Sorry I forgot to respond. And yes I know its every 24 hours lol. Although I wish it reset at midnight. I have to miss a vote every now and then because of the current set up which is extremely annoying. Ps. I use chrome on my phone and it normally works fine
