Looks good again @JB1905, cheers!

I think I know the answer to this, but does the setCellularData action display in the Shortcuts app as 'Set Cellular Data'?

I only ask as it's showing as 'Set Mobile Data' for me - I'm guessing is a localisation thing as 'mobile' is definitely a British thing (my region), and 'cellular' is more American. It's not something I'd considered before now.

[JB1905]

For the USA region it's visible as 'Set Cellular Data'. Also identifier name is is.workflow.actions.cellulardata.set

Cool, we'll stick with that then, as there are probably more users on the US region than UK. Thanks for checking 👍
