I think this bug appeared in the latest JRemote (3.35). When you invoke the "info" overlay by tapping the circled "i" in the upper right when viewing either a list of songs (e.g. the contents of an album) or the current "playing now", there is a column in the middle of the screen with a circled "i" for each song in the list. Previously you could tap on a song's circled "i" and you'd get the info for that song. At least on iPad, this latter op no longer works: tapping on a song's "i" is now exactly like tapping in the song itself. When viewing a song list, it's an "+1" or "play now" etc., per current configuration. When viewing the "playing now" list, tapping on a song's "i" plays that song immediately.
I'm pretty sure this is new for JRemote 3.35. IPad 8th gen, iPadOS 14.4. Happens in both portrait and landscape mode.
Updated with screen shot; the column of circled "i"s in the middle of the screen - one per song - is the problem.
