I have a flutter application that I need to publish on playstore. It uses firebase firestore as it's Database, and also uses snapshotListners. The number of reads during the developing phase (Three developers) was around 2k-3k. But when I submitted the App for review along with the demo login credentials, the number of reads increased to 51k in the following 3 hours. Is my suspicion right?
As part of the review process of your app it may be run in automated (and possibly also manual) tests. So if your app reads from Firestore when it is used, it is indeed expected that this will happen during the review too.
