Hmmm big issue. Downloaded the app. Tried to sign up. Enter in details checked all the buttons... Got to the prove I'm not a robot.. Clicked all the correct pictures. Went back a screen, then back to prove I'm not a robot.. Did this 4 times. Clicked the sign up in a browser, which did nothing still kept me in the app. Left the app, tried in the browser.. Same thing 🤷🏻‍♀️ I guessing you might want to look into this?
