I've been concerned about using this app on my Windows Phone for a while now given the rumours that it steals Ether but after the update today I'm 100% sure I'll never use it again. The app update removed all of my wallets and I'm unable to restore them from backup! Glad I wasn't storing too much on it but DAMN.
Basically, don't use EtherWallet for Windows 10.
Honestly never really had a need to use Ether on my mobile phone anyway but it sucks that there isn't a quality option just in case. What Ethereum wallet do you recommend?
