Thanks for the reply Ivan. Yep tried all of this - and what’s being asked for above doesn’t work.
And for what it’s worth - Asana confirmed that this does not work. Their reasoning:
“*…the Action/result of one Rule can’t serve as the Trigger of another Rule – meaning that moving a multihomed Task to “Section: In Progress” in Project A will trigger that Task’s Custom Field to flip to “Field: In Progress”. However, that flip to “Field: In Progress” will not trigger that Task to move to “Section: In Progress” in Project B even though that Rule also exists in Project B, because the Field flip was the result of a Rule/automation.”
Put differently - this only works if you manually change the field (not through rules/automation). I don’t see any setup where if you move tasks through sections (columns) in Project A, the same task automatically moves through sections in Project B.
This is a strange and frustrating limitation imo - but hoping someone in the community has a verified workaround. Side note: Flowsana has confirmed they support this use case.
