Hi @connor & thanks
My iPhone is an X and has about 5gb of free capacity.
No VPN was enabled on the phone or the network when crashes happened.
Roon Remote works perfectly, zero crashes in my home network.
I have a non solved playback issue described on this thread https://community.roonlabs.com/t/please-suggestions-to-solve-time-lag-on-track-and-album-changes/198147
The issue happens seconds (30-40?) after the phone switches from cellular to home network.
When restarted after crash, ARC works seamlessly over the home network
