I also had a Sim living on "The Shipping Views" lot and did run into cancelled actions.
This was especially noticeable when routing is by ladder.
My Conclusion: Actions that may require holding an object to take it to another level will cancel.
Using ladders will not allow Sims to 'clean up' or take out trash. The default action is to carry dirty dishes or trash piles. You will need a sink on each level to clean up dishes. Trash piles require you to direct your Sim to put it into their inventory or drag it to ground level to be taken out.
May not be a solution but it worked for me.
