Method 1 didn't seem to work, even after a cache refresh both in the UNA app and on the browser level.

Method two worked like a charm, tried auditing the rest of the resize instructions that I didn't think I would need and they all seem to be working.

This might be a very niche feature request but might I suggest adding in an option within Studio to enable/disable the resize instructions that would remove/add those entries from the database table depending on a toggle switch is enabled or not?
