Daily email verifications, saying I "logged into new device"
This is less for twitch and more for the users looking for a solution.
I've been having this issue for months and stopped using twitch for a long period of time due to the constant verifications every time i open it up. Always from the same pc, same connection, etc. Never used incognito or cleared my cache as people said.
I seem to have found a solution that fixed this for me yesterday; I got the idea to remove my chrome extension ad-blocker. It seems to have worked so far so I hope it'll help out at least a few people.
A different ad blocker that wont cause this issue (and is arguably better than the other I used) is called "uBlock Origin".
If this doesnt work for you, then I got nothing.
