Arize AX Trace Delay and Orphaned Span Issue with Google ADK Integration

Hi all! I am using Arize AX using Google ADK. Last time I ran with this code, I was able to see the trace instantly in Dashboard. However, I don't know if anything changed past few days, but I ran again (same code) and now it says my span is orphaned. Eventually after like an hr or two, I start seeing those old traces fine (not orphaned) in UI. Has something changed especially openinference side that is causing this delay?
