OpenClaw version: v2026.3.2

I am seeing Telegram DM streaming behavior that appears inconsistent with the current docs.

Expected

• With Telegram streaming enabled, a text reply should preview in place.
• For a text-only final reply, the same preview message should become the final message.
• I should not get a second duplicate text box for the same content.

Actual

• I see a streamed preview message first.
• Then OpenClaw sends the same text again as a separate final message box.
• Then the original streamed preview disappears a few seconds later.

Observed config context

• channels.telegram.streaming: "partial"
• When channels.telegram.blockStreaming: true, preview streaming is suppressed entirely.
• When blockStreaming: false, the duplicate preview/final behavior can occur.

Why this looks like a bug

• Current docs describe Telegram preview streaming as an in-place draft/finalization flow for text replies.
• What I am seeing looks more like the final text is not reusing the preview message as intended.

Questions

• Is this a known Telegram preview -> final fallback issue on v2026.3.2?
• Is there a recommended config combination for Telegram that keeps preview streaming without duplicate final sends?
