Roon ARC crashes on Iphone

Hello,
In the last couple of years I ahve been trying to get Roon ARC to work on my Iphone (11 & 15), worked through a varity of operating systems, reinstalls ,etc, etc. but nothing seems to work.
The only way I can get Roon ARC to work, is playing downloaded content in airplane mode. That’s grat when I’m on an airplane but in connection with carplay in my BMW, it’s not stable. It’s not even stable when I use it a standalone, listening to my bluetooth airpods.
Last week my BMW get a complete reprogramming but not resolution there…

Any advise on getting this solves would be appreciated.

I have similar issues and interested to hear resolution.

Have either of you tried Tailscale?

If not, it will likely solve your problems.

Doesn’t make a difference, the app already crashes on startup

I find it unacceptable that ARC after so many years does not work reasonably well. On an iPhone 14 Pro Max it is chaos. Within a few minutes the phone is absurdly hot and the battery is plummeting. ARC crashes frequently and within a few minutes it closes abruptly. The solution is to uninstall and reinstall the application, but with that I waste hours waiting for it to synchronize with the server the first time. I have been doing a new installation every week but it is not possible to keep it that way.

The most ironic thing is that on an iPad Air 4, with inferior hardware and using an iPhone version of the application, ARC works well.
