Your question is incredibly vague. If Saadet's link doesn't help then we need more information such as the platform you're using, version, etc. I send faxes regularly. The app is updated often, but I think it's a stretch to say that they updated "everything". It looks a little bit different.
As I'm writing this, I'm thinking you may be referring to the change on the website where you now get two choices on login - the user portal and the admin portal. It is misleading and I don't like that they have masked glip as the user's portal. If this is what you're referring to, go to 'Admin portal' and login there. It should take you to the interface you know and love.
