It's always more convenient when a mobile wallet is synced with a desktop version. I'd just skip those wallets who don't have either. C'mon guys, it's called customer service
but what kind of wallets doesnt have that feature ? all wallets that supports mobile and desktop can sync your account or coins but if they only support one platform then its not possible . and you called that customer service ? why ? costumer service means someone will respon on your concerns . its already fine calling the feature convinient . i use mew before but i heard lately that mew already released thier mobile version ? the one that is app based but i havent tried syncing my coins yet .
I heard mobile version of MEW wallet is MEW connect but it might have some bugs because when it was released lot of issues there so better stick with the plugin MEW for better user expereince.
