Hi there! I see you're encountering an "Oops" error message with an X on your screen while trying to watch a movie on the Hallmark app. I'd be happy to help you get this sorted out. Just to get a clearer picture, could you tell me a bit more? For example:

- Does the error happen immediately when you start a movie or at a certain point during playback?
- Are you connected to Wi-Fi or using Ethernet?
- Have you tried restarting the app or your Mac already?
- Is this happening with all movies or just specific ones?

Once I have a bit more info, I can guide you step-by-step on how to resolve this.

Meanwhile, some common causes for this kind of "Oops" message on Hallmark+ could be related to internet connectivity issues, app glitches, or account authentication problems. Here's a quick start:

1. Check your internet connection — Ensure you're on a stable Wi-Fi or Ethernet connection. You can try loading a webpage to confirm.

2. Restart the Hallmark app — Fully quit the app on your Mac and reopen it.

3. Restart your Mac — Sometimes a reboot clears temporary glitches.

4. Update your app — Make sure you have the latest version of the Hallmark app installed. Since you're on OS X 10.15.7, compatibility is important.

5. Clear app cache (if possible) — Although the Mac version of the app may not have a visible cache clear option, restarting often helps.

If these don't help, there might be server-side issues or account-related problems we can investigate.

Please let me know what you've tried or if you experience the message at a specific time, and we'll dig deeper from there!
