Are you having to force close the Roon 1.8 Remote on iPhone? I have had to do this off and on as of late as it has been freezing on my iPhone 12 Pro.
Yes it freezes.
Yes, often on iPhone 7
Similar problem on Android (Huawei P20 Pro).
Sometimes when I try to start Roon, I get the initial screen and then nothing. The only way to get it working again is to go into app settings, do a force stop and then clear the cache.
Yes, since the update to 1.8 this happens on the iPhone Xs Max too, latest iOS update installed.
Since 1.7 for me and my wife both on iPhones
Maybe related to this thread -
Yip been happening to me the last few days on iPhone 12 Pro
My wife and I both have to do this a lot on Andriod over the last couple of days.
