Chaseway

I press start and it gives me the options continue or login I press login and nothing happens I can press start again and the same 2 options pop up

I'm playing the pathfinder game app on my iOS devise. I've finished the first adventure section and wanted to go to the next but I need to purchase the next section. I was unable to go to the shop area of the app because I wasent logged in, so I created an account on this pathfinder obsidian site. But when I click "start" and it asks if I would like to continue or login . Clicking the login button did nothing for me. Any help? Would love to get that next adventure section
