Added a second Indoor Cam 2K Pan & Tilt but can't add it to HomeKit

I bought a static Indoor Cam and a Indoor Cam 2K Pan & Tilt a few months back when Eufy announced HomeKit support and they’ve been working great. So I’ve now added a second Indoor Cam 2K P&T, which works fine in the Eufy Security app, but it doesn’t give me the option to add it to HomeKit.

After I installed it, it updated its firmware to, and stopped there. My first one is at, but the new one is not picking up that version. I can only assume this is the problem.

Has anyone else seen this? Any ideas for tricks that can kickstart this thing? Thanks.
