Me too. Same issue. Using an Innous Zen as my Roon core. iPad always disconnecting in between songs. Seems like I have good enough signal from my router.
I have tried powering on and off everything. It only provides a temporary fix. I have to power down the iPad and reconnect. I haven’t had much time to listen to music lately, but every time I do, I have to deal with this.
Just had a customer over yesterday and he said he discontinued his Roon service for this very reason.
