The sections of screens throughput roon that can be clicked to hide popups is inconsistent and in need of attention.
A good example is the volume popup on ios, but the same applies to nearly all popups on the mac app aswell. Once you click the volume icon, you can only get rid of the volume popup by clicking in very specific parts of the screen - makes no sense and is not intuitively where you try to click while using the app.
Areas in green can be clicked to clear the volume popup - areas in red can’t.
Just 1 of 100 examples of careless and sloppy roon app development.
In iOS, if you click on the volume icon again, does it not close the popup?
This is what happens in Android and Windows (and for me it’s very intuitive).
I just checked and confirmed on my iOS app for my iPhone and my iPad and both behave consistently and similarly to my Mac and Windows applications: click anywhere on the screen and the pop-up window closes.
What version of iOS do you have, what version of iPhone, and are you on the current Roon build of 943? Same questions for your Mac.
Is it worth updating iOS to 15.5? Probably not going to change anything. Another option may be to delete Roon from your iPhone and reinstalling it. I haven’t seen this behavior on my iPhone 11, so you may need to wait for Roon support to respond.
I’ve noticed the same behavior on my iPad 7th gen, currently on 15.5, but was present on 15.4 as well. Sometimes I have to “hunt” where to click to close a popup.
It hasn’t always been this way, but I don’t remember exactly when it started (sometime in the past several months maybe?).
In my case, I’m on latest iOS and Roon versions (iPad 7th gen and iPhone 12 Pro) and am seeing the behavior as described by the OP. In the scheme of things, it’s not a big deal, but an annoyance (among others).
