Hi there! I understand you're having trouble with the time and date selection not opening during the checkout process on Jewel-Osco Delivery & Pick Up. That can be a bit inconvenient, but I'm here to help you sort this out.

First, can you let me know if you’re experiencing this issue on a specific browser or if you’ve tried using another one? Sometimes, switching browsers can make a difference.

Here are a few steps you might want to try:

1. Clear Browser Cache and Cookies: Sometimes, your browser’s cache can cause issues.
- Open your browser settings.
- Find the option for "Clear Browsing Data" or "Clear Cache."
- Ensure that "Cookies" and "Cached Images and Files" are selected.
- Clear the data and then reload the Jewel-Osco site.

2. Check Browser Extensions: Occasionally, ad blockers or other browser extensions may interfere with website functionality. Try disabling any extensions temporarily and see if that helps.

3. Update Your Browser: Make sure that your WebKit browser is updated to the latest version. If you need help with this, let me know your specific browser version, and I can guide you.

4. Try Incognito Mode: Open an Incognito or Private Browsing window. This mode doesn’t save cookies or site data, so it might help bypass whatever’s causing the issue.

5. Check for System Updates: Ensure your Windows 10 OS is up to date with the latest updates. They sometimes include fixes for browsing issues.

If these steps don’t resolve the issue, or if the times still aren’t showing, it may be worth checking with Jewel-Osco’s customer service for any ongoing technical difficulties. You can reach them at 877-505-4040, or you can visit their Help page for additional support.

Are you able to try these steps? Let me know what happens!
