Alright everyone, the issue has been resolved and the button is working as designed. I did a few trial runs on Discord (easier to do in real time than on GH) and it was a success. I've patched the previous bugs that were causing people to be unable to enter for whatever reason, and it's been tested across various devices and browsers. If you happen to encounter a particular problem, please PM me directly about it so I can address it. So far, I think things are working much smoother.
In any case, if you are somehow unable to access the Sale Form, simply type in
www.keyforge.com/saleform. This will give you direct access, but I would advise using the button first. PLEASE PM me if you are forced to use the direct link. Otherwise, the button should suffice.
The only issue that I cannot repair at this time has to do with iOS, and closing your phone while on the timer. If you do that, the timer will lag behind until you refresh the page. This is only a problem on iOS devices, so if you are entering from your iPhone or iPad, then please make sure you refresh the page after closing and opening your device.
Other than that, you don't need to watch out for anything. You are free to refresh the page as much as you want, and you can even refresh once on the Sale Form page. Nothing will prevent you from being able to push the button to enter the sale.
Thanks again for all of your patience and kindness in regards to this issue. I'm continuing to make the website better in small ways, and I hope this helps going forward.
