Hi Evernote team,
I encountered the exact same problem.
After I clicked sign in the page keeps saying "Loading...", both on Google Chrome and Safari,. I tried clearing cookie and browser data, logging in anonymously but to no avail.
When I tried to create a new account it gets HTTP ERROR 418, also I could not sign in to Desktop version as well, it tells me to upgrade the version all the time although I've already grabbed the latest one.
I asked my friend and he said he could log in normally with his account so I have no clue why mine wasn't working.
Could someone please address these issues? Thank you so much!
