Currently you cannot navigate await from the screen that says "Waiting for your link click", so you will need to open the email in a different app than your browser, or in a different tab.
Sorry about the trouble, I will make this more clear in the UI. If you want you can email me at contact at langturbo dot com and I can look into it.
Note that you track your progress seeing the minutes played and the words marked as known when you click on the button on the top right in the "Profile" tab.
I don't have a mailing list at the moment, but I will create one and send product updates to the people that have accounts, so if you create an account with your email I will send updates that way.
