Not sure if it was a coincidence, but I also constantly had that overloaded message and I deleted and re-installed the app and never seen it again.
Oh really, I should try that then. I am however still seriously concerned to the ETN decision of using this kind of "bank account wallet"
You don't have to use the online wallet, just create an offline wallet and then transfer your ETN to it.
Of course I don't have to. But MOST new people WILL use the online wallet, since electroneums main audience are new users and mass adoption. So this IS a big security risk, because if the electroneum servers gets hacked, hundreds of thousands of people might lose their funds and that will definitely have a negative effect on electroneums reputation and mass adoption aim.
