Google Analytics - Issue with User-Specific Data not Appearing in Google Analytics Console

[InvescoTeam]

I've encountered an issue with Google Analytics in my React Native app, specifically related to user-specific data not appearing in the Google Analytics console. I have implemented custom dimensions to track specific data points, but I am facing difficulties with few particular user's data not showing up. Here are some details about the user's mobile device:

Operating System: Android
OS Version: Android 12 Mobile
Model Name: Samsung Galaxy M51

Code:
const response = await analytics().logEvent(eventname, params);

"@react-native-firebase/analytics" :"14.11.1."
"react-native": "0.66.0"

Could someone please assist in understanding the root cause of this problem and provide guidance on how to resolve it? Any insights or suggestions would be greatly appreciated.
