Hello @Dione,
can I also connect my FXWallet securely from my iPad/MacBook (tablet/laptop) or is it only recommended to connect from my Mac (desktop) !
Merry Xmas - Greetings Belgiumguy 
Works best with desktop/laptop as mobile browser on tablet/iPad may not work as intended. Dev team will be working on mobile web version down the road.
Hello - Thanks @orbitant for the clarification - Enjoy the end of year celebrations 
Greetings Belgiumguy
