Apple Watch remote keyboard (iPhone): pasted text arrives empty on the watch, typed text works (watchOS 27.2)

When a text field on Apple Watch is filled through the iPhone's remote keyboard, text that I PASTE into the iPhone field is displayed correctly on the iPhone but arrives EMPTY on the watch. Typing the same text character by character works fine. This happens in both secure (password) fields and regular text fields, so it doesn't look like a password-field restriction. Steps to reproduce

  1. On the watch, open a text field (I tested a password field and a regular one).
  2. Open the keyboard on the iPhone when prompted.
  3. Copy a short test string (e.g. "test12345") from another app.
  4. Paste it into the iPhone field. The iPhone shows the text.
  5. Confirm on the watch.

Expected: the watch receives the pasted text. Actual: the watch field receives empty input. What I tried

  • Typing the string by hand: arrives correctly.
  • Pasting in a secure field: arrives empty.
  • Pasting in a regular field: arrives empty.

Environment

  • iPhone 15 Pro Max, iOS 27.0 [confirm current version]
  • Apple Watch Ultra 2, watchOS 27.2 (24S5091f)
  • MacBook Pro (M1), macOS 27.2

Has anyone else seen this? Any workaround other than typing the text manually would be appreciated.
