Is this really required? Have you seen any app that hides the register button to load the progress bar like this?

I think it prevents user from spamming the button and sending multiple requests. We can also disable the button when it's clicked, but I think this looks better and also provides better location for progress bar.

Then disable the button while progress and change its color to something dull.

Should I remove the progress bar entirely then?
