Description Of Issue

On my iPhone, at times, the Roon App will constantly crash. I will start it again, navigate for maybe 15 secs, then it crashes again…and again…this can repeat 12 or more times. Powering off the iPhone seems to helps some, but the problem reappears. I had the same issue on my iPhone 11, I recently upgraded to the iPhone 12 Pro. I do not have the issue on my iPad nor does it occur on my Windows 10 laptop. It occurs regardless of which playback device I select.

Please assist. I am happy to pull logs etc.

Thank you for the report here, we are tracking this behavior in the following thread, please let us know here for further troubleshooting:

I can confirm similar behaviour (iPhone 12pro). May be ok for some time (even days). When it starts a reboot of the mobile is the ONLY way to fix it. Switching languages does not. This has been happening over different versions of the mobile (XR → 12p), Roon (1.6 → 1.8) and server hardware (iMac w/ High Sierra → Synology).

To me the only common factor is the very same iPhone setup (carried along by backups from one to the next). Other devices in the house (6s and iPad 6gen) seem not to be affected at the very same time. However starting with the iPhone from scratch is no option. Roon simply needs to be more robust.
