This has happened repeatedly since updating to v1.2. See screenshot.
Someone has a microRendu early!
Have you uninstalled and reinstalled the app. I think that fixed it for me one time when I was seeing it in 1.1
Conversely, v1.2 is the first ever version for me that seems to have totally removed the blank screen occurrences. Not once since upgrading have I seen it, whereas I’d encounter it at least daily with all previous versions.
I did also update to the latest iOS this week too, perhaps both are required?
PS well spotted @DrTone. Chris, we hope there will be a microRendu first impressions topic soon… 
I have exactly the same problem. It happens mostly when coming from standby. I use a 2016 9,7" iPad Pro.
Mine’s on an iPad Air 2. For me it happens after standby, or after switching Apps.
Going to try Dr Tones suggestion tonight.
I use an iPad Air 2 as well.
I’ve seen this also. I’ll get a ticket raised.
There’s no ticket already!!!??? 
It’s been around a looooong time….
I’ve had this happen on my home system as well, often… but i cant reproduce it in a test environment…blah.
this bug is horrible.
I forgot to send update - I tried the advice of deleting Roon ap from iPad then reinstalling from scratch a week or so ago.
Annoyingly I forgot I’d done that, so haven’t been paying attention but I’m feeling like I haven’t noticed blank screens since. Will pay more attention next few days.
I had it happen on mac too!
Ah. I used to get that too but I so rarely use the laptop for Roon nowadays I couldn’t say if it’s still occurring.
This problem is getting pretty annoying. Almost every switch back to Roon (latest buld) from another app on iOS (iPad Pro 2016) gives me a black screen and also the back and forth navigation is lost. Any fix coming up, @danny?
Other than this, really enjoying Roon with a microrendu as endpoint right now!
@willemzout have you tried deleting the app from the ipad, and re-installing it as mentioned above?
I know that’s often the default solution people suggest as a fallback, but in this case I’m pretty sure its worked for me. I haven’t seen a blank screen on the iPad since I did it anyway…
@hifi_swlon This seems to work indeed, thank you! Tried this before, but I guess with the latest build it came back, or just after a while.
working on reproducing this in-home… I’ve had it happen to myself at home, but not in a controlled environment. The bug is extremely annoying, and I’d like it resolved asap, but right now, we are still trying to reproduce it in a controlled environment so we can figure out what’s going on.
found it and fixed! whew. Next build…
