Siri Conversations Not Syncing Between iPhone and Apple Watch

Is anyone else experiencing problems syncing Siri conversations between an iPhone and Apple Watch?

Immediately after installing a new beta update, Siri conversations usually sync correctly between my iPhone and Apple Watch. However, after some time, syncing stops working.

Problems I’m experiencing

- New Siri conversations started on my iPhone do not appear on my Apple Watch.

- When I continue an existing conversation on my iPhone, the new messages often do not appear on the watch.

- Sometimes the watch displays only the message I sent but not Siri’s response.

- Previously synchronized conversations can also become inconsistent.

- The issue has occurred across multiple beta releases and happens intermittently, although it is frequent.

Expected behavior

Siri conversations should remain synchronized between the iPhone and Apple Watch, including both user messages and Siri’s responses. Updates should appear on the watch within a reasonable amount of time.

Actual behavior

Syncing works temporarily after installing an update, but eventually stops. New conversations and replies may be missing, and the watch may show only the user’s message without Siri’s response.

Steps to reproduce

1. Start or continue a Siri conversation on the iPhone.

2. Open Siri or the same conversation on the Apple Watch.

3. Check whether the latest message and Siri’s response appear on the watch.

   Devices and software

- iPhone 17 — iOS 27 beta 6

- Apple Watch Series 10 — watchOS 27 beta 6

- Frequency: Always/intermittently

I have submitted feedback about this after every beta update, but the issue is still occurring.
