A. To address frequent crashes, ensure that your device has sufficient storage space. Go to Settings > Storage and check if you have enough free space. If not, delete unnecessary files or apps to free up space. Additionally, regularly restart your device to clear memory and improve performance.

B. For slow syncing, try connecting to a stable Wi-Fi network instead of using mobile data. This can improve the speed and reliability of the syncing process. Also, avoid using the app while it is syncing to prevent additional strain on the app.
