I have purchased Navionics Europe HD app. I have been using this app years and it has been working fine until now. When I open the app today, it says this app will no longer receive updates and that all my charts and data have been transferred to Boating Marine & Lakes app. When I open that Boating Marine & Lakes app, it suggest that I should log-in or registrate. When I try to do (both options) it just open blank page an nothing happens. I’m on my sailing vacation I cannot plan my routes. Extremely zero user experience.
