iOS SDK Thread priority inversion

After installing and integrating the Smooch SDK into our iOS app, but before the messaging window is invoked, I am getting this run-time Hang Risk issue in Xcode:

/Users/conor.nolan/Code/sunco-ios-private/Smooch/ThirdParty/SocketRocket/SKTSRWebSocket.m:1851 Thread running at QOS_CLASS_USER_INTERACTIVE waiting on a lower QoS thread running at QOS_CLASS_DEFAULT. Investigate ways to avoid priority inversions

The stack trace looks like this:

Please advise how I can avoid this hang risk.
