Having just upgraded to 2.2, I’m noticing sync issues between the embedded and pop-out transport bar, as you can see in the gif below. I’m also unable to edit the fixed tempo in the pop-out transport bar.
It’s correct (and documented) that you can’t edit the tempo value in the Transport window at the moment: this is something we will implement in future. You should find that the values do sync up as soon as you start playback.
Ah whoops, my mistake on that one then!
