Do you keep forgetting where in your home you left your phone? Find my phone is a great feature until it stops working, now you have to find your phone, wallet, and car keys without any help. Yes you can use Tile, Chipolo, etc. to help you find those other things, but I digress.
Seems silly to make an entire blog post for this issue but after Google Home support was unable to help and I could not find a solution in their help center or anywhere on the internet, I figured they may be others having trouble.
Below is the link to Google Nest with the basics of getting "Find my phone" to work.

If you are still having trouble, you may have the same issue I was having. Before giving you my fix, here is a little background. "Find my phone" was working fine from my Google Assistant enabled device but I was having another issue. Google Home does not like you to use a Google Workspace (previously G Suite) domain account. If you do, many features will not work including what is on my calendar.
I had been using my Google Workspace account with Google Home, so switched to using a gmail.com email address and many features started working. Calendar works but requires some fun settings if you want access to your Google Workspace calendar. Share your Google Workspace user calendar with the gmail.com user and give read/write access. Then in Google Home make that calendar the default for adding to the calendar and make sure to make that calendar visible.
Ok, back to trying to find your phone. Once I switched to a gmail.com account, the Nest Hub and Nest Minis could no longer find my device. I looked through settings and could find no solutions. I then went to https://play.google.com/settings/ and found the problem ... my Google Workspace domain account had my device listed under "My devices" while my gmail.com did not. Found no way to fix this issue, so did the old stand by ... almost like a reboot, hahaha. I removed the gmail.com account from my device and then added it back and this time it showed up under My devices in Google Play and now "Find my device" works. That easy.
Now where did I put my beer.
