posting this here just in case -- i'm a Mac user and am having the exact same issue, the game (or moreso the login tab) was completely fine a few days ago and then just suddenly went out on my end- ??
-im using Chrome
-i cleared my cache + cookies multiple times
-logging in on a different device doesnt work
-my info/login is fine since it works on the actual FH page/dashboard(??)
-ive reset my wifi as well
im not sure what to do,, this wouldnt be a big deal to me if i didnt have something super important to do ingame with friends, but im just getting kinda,, i dunno- hoping its fixed soon- ;-;
