Growing. 2 reports and thumbs-up in the last 7 days and 1 the week before. A workaround is known.

Reused subagent loses in-app browser after normal completion. After a subagent finishes, a follow-up to the same subagent cannot find the browser and reports "Browser is not available"; a fresh subagent works.
