Layers on IOS app

I’m using the coastal explorer app on my iPhone and when I go to import layers it won’t import my chart files, the only thing I see is the syncing icon on top of the settings button, I’ve tried deleting and reinstalling and signing out and still it does the same thing

Hi there. Welcome!

What do you mean by “chart files?” Are you referring to routes, marks, etc., the things you’ve created, or do you mean nautical charts? Thank you!
