Working doorbell no longer working

Have had doorbell/cam working without issue for a month. Homebase 2 . No issues. Added 2 floodlight cam option to household.

Ever since doorbell disappears from my device list. Have to manually readd .

Left doorbell nearer Homebase for 15 minutes no issues.

Soon as I relocate it to its original outside position . It beeps once dark blue ring and disappears from my devices list in the app.

Why would something that has previously worked with out issue, potentially be impacted by the new additional device, as that’s the only thing that has changed??
