Roon ARC stability issues

This is affecting a lot of people apparently, here is the oldest thread about it:

Roon & ARC have become incredibly unreliable for me - what is going on?

I went on holiday three weeks ago, and already after two days my core was unreachable with ARC. Luckily, I have a lot of music downloaded to my phone (Android), which I can play in offline mode. I experimented with ARC on my iPad: after resetting ARC there, and even after deleting the app and reinstalling, I get the message that my core is ready, but after clicking connect, there is an endlessly spinning circle. I have tried to connect multiple times over several days, over different connection…

Has been an issue for a while, unfortunately
