This specific issue was found in C#'s keepalive implementation, it sends a blank message instead of a ping which seems odd. I'll send an example sometime today

 I was actually able to reproduce on the production bridge server. Can you confirm this is the right place for this change?

@JASchilz a fix has come [#141](https://github.com/KartikTalwar/Duolingo/pull/141) :)

this is related to deep linking to a wallet which this library doesn't currently support, but we plan on adding support (unity already has this)
