Windows 8/8.1/10 voting problem

Here is how I vote everyday:
- My main account that I need the most NX on I vote on my PC. I use google chrome but every once in a while it will fail and I will use Microsoft Edge and it goes through. I never vote for any other account via PC because it can cause issues.
- I turn data off on my phone and vote on my 2nd main account on google chrome.
- I airplane mode on, then off, and vote on my 3rd account using firefox.
- I airplane mode on, then off, and vote on my 4th account using microsoft edge.

Again, I never try to use a different account on each of these devices. There are reports that GTOP may be able to link the IPs and will block them. I don't know if this is true or not but I do it as a precaution. Its very rare now that one of my voting methods will fail, but if it does I just don't vote on that one for that day and proceed to the next ones. You won't lose a voting streak over missing one day, though it does suck to not get NX. But if you start mixing accounts over different browsers it might cause issues (unverified).

Browsers that work for me are: Google Chrome, Firefox, DuckDuckGo, Opera, Firefox Focus, Brave, Safari
