Works fine on updated iPhone X with Roon 1.6.
Cannot even start the app on iPad Pro 2018 12.9", an older iPad and yet another, even older one. Just installed on an iPad Mini.
Also, iMac crashes immediately. Same on MacMini. Also, just tried installing it on an older MacBook Pro and it allowed me to find the Nucleus and connect. But when I chose a zone it crashed. Any attempt to launch it again caused the app to crash. For grins I used the same MacBook but launched Win10 under BootCamp. Installed Roon and it got as far as asking for Zone. Once picked it crashed. Subsequent attempts to launch the app reveals the black box with roon and the random quote, a white box appears with red X across it and then crashes Likely this is different than Mac environments due to the fact of Win10 implementation and slower laptop.
Thinking it might be my network, I powered off my cable modem to Comcast as well as WiFi access point devices. Powered the cable modem on and waited a bit. Then the access points. No change in situation.
What can I do to find the source of the problem?
Update: tracked the problem to the dCS Upsampler. When I installed the app on the iPad Mini rather than immediately pointing it at my dCS Zone, I tried a couple others. They worked without a problem. So, isolating to the dCS Zone, I restarted the Upsampler along with the DAC. After that, all is well.
No idea why everything was OK yesterday, but suddenly went crazy today.
