Steve,
Actually, I beleive this is a CC issue... but Who Am I? In any event...
I have not been able to Sync.
I have had only one Adobe ID (since around PS 3).
My Network Connection is fine (if evidenced only by us communicating.)
I have quit and lanched PS probably 20 times since I discovered this issue last week.
Thank you for taking the time to help me.
Ron
