All this development and bright new shiny features are great. What's not? The desktop wallet client. It works fine for you? Well good for you.
I however get the "transfer transaction could not be created" from time to time. With no hint or explanation into the actual cause. And then it suddenly just works. This code should be much much more robust, or you could at least give us more detailed error descriptions. Thank you!
The ARK Wallet doesn't force you to connect to a centralized peer like most wallets. Due to this, sometimes you can end up with a connection to a bad or outdated peer. Usually in that situation, updating the peer with the cloud icon will solve it. You can also select a dedicated peer from the community and set a custom peer with the cloud icon to help avoid it.
