That's not accurate for the mobile SDKs. Mobile SDKs use an offline cache, and you don't have to call close before the app exits. All SDKs ensure that no data is lost when the app is put to the background and / or exits. The close method on mobile SDKs exists so users can manually close the SDK. Close shuts down the SDK and tries to send all data to Sentry. Most of the time users don't have to use this.
