Thanks for the advice – I disabled and checked through the other add-ons and found the culprit! Card Elements for Elementor stopped the Download Manager options from displaying. I can’t seem to find on my site where I need this add-on so I’m sorted and hope it’s helpful to know which one it is so you can do some digging on why there might be a conflict. I will also get in touch with the add-on provider to let them know about this glitch.
