I seems I cannot remotely clear the Safari cache on non-shared iPads, but I'm close to finding an alternative solution.
Ojisan Seiuchi has found that when iOS Safari is presented with a URL in a certain format, it will execute preference settings on the device.
Settings → Safari → Clear History and Website Data has its own URL and by loading that URL through an iOS Shortcut created using the Shortcuts app, you can quickly clear Safari. This worked immediately for me.
Now I'm looking for a way to deploy that shortcut via JAMF Pro. Any suggestions will be gratefully received.
