NAVA now uses agentic workflows since the end of last year, and the "AIA Unified Planner Quick" and "AIA Unified Planner" are now shared between NowAssist in VA and AI Agents. Typically this issue is caused by missing AI Agent capabilities or a communication problem with LLM provider, when it is stuck on "Thinking..."

1. Ensure the application "Now Assist AI Agents" is up to date, as there may be missing AI agents capabilities in the [sys_one_extend_capability] table that prevents it from progressing further.

2. Check the sys_alias and http_connection records for the LLM configured for NAVA, especially if using a BYOK (Bring your own key) for your LLM.

Hope this helps.
