On Change Update Query

I am using the on-change update query in Firestore database, but it continuously triggers even when no updates are made to the document after any single conditional action.This issue persists even when there are no updates being made to the document. I am not sure why this is happening, please help. This problem is so critical that if it exists in a large-scale app with 10,000+ users, the Firebase pricing would skyrocket, making it unaffordable.

मैं on change update (firestore database) query का उपयोग कर रहा हूं जब on change update पर किसी single conditional action के बाद कोई भी update लगायें या न लगाएं। यह लगातार on change update दिखाने लग जाता है जबकि उस document को कोई भी update नहीं कर रहा है । यह क्यों हो रहा है पता नहीं चल रहा है please सहायता करें ।
