Steps to set up and reproduce

We have developed an Ionic Hybrid app for iOS, Android, and Web platforms, which has been functioning smoothly for the past two years. However, after multiple library updates, we have encountered an issue specific to Android devices. Retrieving the first fresh snapshot listener takes an exceptionally long time on Android, whereas iOS and web platforms retrieve the same snapshot listener in just 1 second on the same device. Android hybrid apps may take up to 60 seconds for this process.

Interestingly, restarting the app after the initial retrieval significantly improves the speed.

I am currently using the compat SDK instead of the Web modular SDK. I wonder if this choice affects the result.
