Hi there! It sounds like you're experiencing slow upload issues with the Bible Gateway app on your Windows device using WebKit. Just to clarify, when you say "slow upload," could you specify what exactly you’re trying to upload? For example, are you uploading notes, highlights, or sharing something through the app? This will help me provide the best solution for you.

In the meantime, here are some general steps to address slow upload performance on the Bible Gateway app:

1. Check your internet connection speed: Sometimes slow uploads are related to an unstable or slow internet connection, even if downloads seem fine. You can test your speed using a site like speedtest.net.

2. Update the Bible Gateway app: Make sure you have the latest version of the app installed, as updates often include fixes and performance improvements.

3. Clear app cache and data: Sometimes cached data gets corrupted and slows down operations. Clearing cache can help reset this.

4. Restart your device: A simple reboot can refresh your system and network connections.

5. Check for Windows updates: Since you’re on Windows 10, ensuring your OS is up to date can help compatibility and performance.

6. Try logging out and back into the app: Sometimes refreshing your account connection helps clear any temporary syncing issues.

If you’ve already tried these steps or your issue involves something specific (like sharing verses or notes), please let me know so I can guide you more precisely!
