Trouble logging in to save curriculum

I am having trouble logging in to start the curriculum. When I click the Yellow Get Started Button, I login using my email and password. But I keep getting this same error message. I also tried logging in using Google since it is a gmail account.

is your browser updated to last version? if not, please update it and try again, if yes, could you try logging in incognito mode?

if that doesn’t work you could try to write at, there may be something gone wrong in your account
