Webhook event latency

we’re using the Video SDK webhook (session.user_joined, session.user_left) to calculate the duration of video calls between two users. However, we sometimes receive these events with significant delays—ranging from 3–4 minutes to over 30 minutes after the session has ended(session.ended).

Could you help investigate the following sessions and clarify when these delays occur?
