Engaging or disengaging loop in transport bar or via a key shortcut interrupts audio playback.
As far as I know, it has been like this for a very long time. Personally, I don’t find it disruptive, but of course it would be better if this didn’t happen.
Yeah been like that forever, but only (in my case) when switching off looping, not engaging it.
It really has to be dealt with as it is literally not possible to do critical listening while engaging/disengaging the function on the fly.
