Hey, thanks for the report. Since Composer 1.5, subagents should work in Auto mode too. Colin confirmed this here.
But we’ve seen reports that for some users it still doesn’t work even on 1.5. You’re on version 2.4.36, so Composer 1.5 should be available for you.
A couple things to help debug:
- Try picking a specific model instead of Auto, like Sonnet 4.5 or GPT 5.2. Do subagents work then?
- Please send the Request ID from a chat where subagents didn’t connect. Click the three dots in the top-right of the chat, then Copy Request ID. It’s best to turn off Privacy Mode while testing.
This will help us figure out if the issue is specifically Auto with Composer 1.5, or something else.
