A. To mitigate app crashes during network changes, ensure that your device's operating system and the Navionics app are both updated to the latest versions. Go to the Google Play Store, search for Navionics, and check for updates. Additionally, try clearing the app's cache by going to Settings > Apps > Navionics > Storage > Clear Cache. This can help resolve temporary issues that may cause crashes.

B. If the app continues to crash, consider switching to airplane mode before changing networks. This can prevent the app from trying to reconnect while the network is unstable. After the network change, you can turn airplane mode off and reconnect.
