Yeah, the advice you get from the attorney often has little
to with the protocol of the Probation Officer, who can be
incredibly obtuse or even lose paperwork.
In my case the attorney said I could take a new job abroad as my US job
expired but the PO didn't like that and filed a Violation. I could not find out the "real" answer because it was not written anywhere in stone.
Bottom line, take it seriously and work it out. The US legal system loves to throw people into catch-22's and you can find yourself in hot water even if you tried as hard as you could to deal with the situation.
