2. I tried to login by reset password, it show error loading page.
3. I tried to login app via email: it's showing that :There was an error validating e-mail..."
4. Login via google account, it's saying I should update version but my current version is the latest.
5. Login via iOS app: it's saying has problem in connecting with Evernote( it has nothing with my internet connection)
