Only hiccup I've had was when I tried ecash straight to aqua and vice-versa in the early days. since then been good.

that said, it's not my daily go-to. Mostly use it to loop back into lightning if sender doesnt have it... And to play around of course.

Coinos just works as well. full custodial but no app required and no initial setup needed.

just go to a webpage and you're ready.
