Apple Watch not showing incoming calls when in Lockdown Mode

Linking to multiple other threads on this forum discussing the issue, that whenever Lockdown Mode is activated on an iPhone (i own an iPhone 15 Pro) and an Apple Watch (Series 10 , but NO eSIM installed on the Apple Watch) incoming calls are not showing up on the Apple Watch.

No notification of an incoming calls is present on the Apple Watch, even though the Phone is ringing, showing the caller ID etc.

The Watch than shows notification of a missed call or of a new voicemail, but during the ringing the Apple Watch is NOT making any noise, vibrating etc.

When turning off Lockdown Mode on my iPhone the notification of incoming calls showed up on my Apple Watch as expected (basically immediately, meaning I am able to reproduce the issue)
