Google Sheet is not updating

Please provide more detail what you mean by that. What steps are you taking and what makes you think it is not updating?

For apps on a mobile device:

1. Open the App Store app

2. Select your icon in the upper right corner

3. Scroll down until you see a list of apps.

4. Click update all or scroll down past the first screen to select individual apps.

If the arrow just spins, here are various things to try:

• Make sure you have a strong Internet connection, preferably wi-fi.
• Completely remove any VPN you are using. Don't just disable it; remove it entirely.
• Restart your device.
