iOS Devices not showing in Finder Sidebar: Monterey 12.6.4; iOS 16.4

None of my iOS devices on the same wi-fi network are showing in the Finder sidebar. Previously this had worked perfectly.

Troubleshooting attempts: restart Mac and iOS devices; uncheck and recheck box in Finder preferences; reset Mac pram; restart wi-fi router.

Device will show if connected to Mac by USB cable, but not on wi-fi as it had before.

Mac OS 12.6.4

iOS 16.4

Hardware: Mac Pro late 2013; iPhone 11

Thank you.
