XiaaLive + BubbleUPNP

Trying to get XiaaLive working with BubleUPNP, apparently fairly straightforward, but am having issues getting them to tak properly. My suspicion is that I have a XiiaLive (3.3.2.1-30059) which was purchased from Amazon, but BubbleUPNP (2.9.4 (arm64-v8a) is straight from the Play Store.

When I try to share to BubleUPNP, it opens the app at the Now Playing page, but does nothing.

Is there a fix for this?

Thanks.
