Are the beats fit pro able to use the “find my” feature for ios?

Currently it only has the basic Find My where you'll need to be near them to have a chance of finding them. There's no integration with the larger find my network or left behind functions that the AirPods currently have.

I thought I had read/heard that that was coming but I can't find any mention of it now?

According to CNET, Beats has said they will add enhanced support:

Aside from the lack of wireless charging and MagSafe compatibility, the only other notable feature currently missing from the the Beats Fit Pro compared to the AirPods Pro is enhanced Find My with proximity view that allows you to precisely locate your AirPods within a few feet of where they might be hiding. The Beats Fit Pro currently have standard Find My, but Beats has confirmed that it's working to add enhanced Find My and the additional AirPods updates that were part of iOS 15.1 in a future firmware update.

Yes, at least it does for me
