Hi mwhite2264,
We understand the Handoff feature isn't working any more, so we'll share some tips to isolate and troubleshoot that issue.
As a starting point, this link covers the requirements for Continuity/Handoff, so I recommend double-checking to make sure everything is set up accordingly: Use Handoff to continue a task on your other devices
Then restart both devices and ensure the software is up to date to rule out any conflicts.

Are there other continuity features that aren't working outside of Handoff? Here they are - Use Continuity to connect your Mac, iPhone, iPad, iPod touch, and Apple Watch.
Thanks for posting in the Apple Support Communities forum.
Enjoy your week!
