A50+ AirPlay latency

I just received my A50+ and am using it for AirPlay to a vintage stereo console exclusively but I’m experiencing about 4 seconds of latency between my phone and playback on the A50+ which is an awful user experience.

The app shows Wi-Fi strength @ 98% and I have no latency issues using AirPlay from my phone to other AirPlay devices. It’s only the A50+ that has the issue.

Is this a known issue and how to I fix it?

Does anybody else use AirPlay? I figured that was a pretty big use case but it seems maybe it isn’t.
