Hey @Wiseman,
Before publishing your app on app store or Google Play, I would recommend testing it on Apple or Google Play’s internal testing. In order to make sure your app is running smoothly, you can check the following points:
- (New React Native Version) is activated on your app’s settings.
- Use more native lists than custom lists, and make sure to activate the (Load items as user scrolls) in your lists.
- Avoid activating the (Auto Refresh) option in your list unless it’s necessary.
- Activate (Pagination) option in your list in case you have a lot of records to present.
- Avoid having a lot of components in one screen, especially multiple lists.
