I can’t even begin to explain how much I appreciate your help, John. You, personally, are seen everywhere across this forum, going above and beyond to provide support to an extent that I don’t see from any support team at all (and doing so for arguably as valuable a plugin as exists). In all sincerity, thank you. It’s nothing short of amazing.
Anyways, using the code you’ve provided above, I can confirm that, yes, the filter is in indeed being called.
