Hello! I understand the VITA app on your WebKit Android 10 device is stuck on the loading screen or not opening. Let me help you get this sorted.

To start, could you tell me if this happens every time you try to open the app, or did it suddenly start? Also, have you tried any fixes so far, like restarting your device or reinstalling the app?

Meanwhile, here are some step-by-step troubleshooting steps we can try:

1. Restart Your Device
Sometimes a simple reboot helps clear temporary glitches. Hold your device’s power button and restart it.

2. Clear VITA App Cache and Data
- Go to Settings > Apps > VITA.
- Tap on "Storage."
- Clear Cache first. If the issue persists, Clear Data (note: clearing data resets the app, so you may need to sign in again).

3. Check Your Internet Connection
A slow or unstable connection can prevent the app from loading. Try switching between Wi-Fi and mobile data to see if that helps.

4. Update the App
Check if there’s an update available for the VITA app on your app store and update it.

5. Reinstall the App
Uninstall VITA completely and reinstall it fresh from your app store.

6. Check Device Storage
Make sure you have enough free storage space, as low space can cause apps to misbehave.

If after these steps the app is still stuck loading, let me know, and I can guide you through more advanced options such as reviewing permissions or checking for conflicts with other apps.

Did you try any of these already, or should we go through them together?
