Hello,
I use a program called Mixup.audio to communicate with others, to let them hear what I changed in there mix, then they can reply and give comment (it places a dot on the timeline where the comment was typed. Musicians can post a new version or play a new part in the song. It works standalone or as a plug-in in your DAW. here is the link to the playlist : https://mixup.audio/playlist/DTXYTjqzN7
yto select another version click on the arrow next to the title (see pictures)
Maybe you can use it, there is also a free version
