With Adeniums blooming does not really mean it is awake. It can still be dormant. Needs to show new leaf formation to truly say it is awake. It may hold on to last season's leaves, but if there is no new growth as well, it is dormant. Or it can drop everything and just be bare.
Yes, I think you can still remove that very soft part till you reach good tissue, and then apply cinnamon once more and keep it dry, no media for now. Got to let that part heal and harden.
My Adenium is dormant right now, have not given it water since December. Just hiding indoors patiently in a south facing room. It really taught me to be very patient and not rush it to waking up. It will do so on its own sweet time by mid Spring.
