Iphone issue

Sorry if this has been asked before. I am brand new to Zwift. I am only using the zwift running shoe pod at this time.

I have used the app on my ipad…However I would like to use it on my iphone 8.

I get to the welcome screen. it has 3 dots on the bottom to scroll to the right. It won’t let scrol to the right, or left. So I am stuck on this welcome screen. Anyone have any solutions?

Thanks, Brad
