Airplay pauses randomly

AirPlay pauses randomly when using my iPhone 8 to AirPlay to a Pi3 with HiFiBerry Digi+Pro HAT running RopieeeXL v3.075 (version was just updated today). Sometimes it’s ~30 seconds, sometimes it’s ~5 mins, completely random as far as I can tell. iPhone is running v14.4. There is no remote enabled on RopieeeXL.

Today, after the software update, was the first time I have enabled Shareport, so there is no past AirPlay history to draw on here. I have never experienced pauses when playing from the Roon Server MacMini to the HiFiBerry. There is another RopieeeXL device on the network, it was not playing anything when I experienced the pausing; the Roon Server was playing to a directly connected device while I was using AirPlay (could be unrelated but just trying to provide as much information as possible).

What can I do to try and track this down? is there some type of log I can see for AirPlay or the Ropieee?

Today no pausing of AirPlay so far in maybe 4 hours of playback. Roon Server is currently not playing anything but application is running on the MacMini
