Hi there! I understand you're seeing a white screen when opening the Hudl app on your Mac, and that this used to work fine before. Let’s work through this together.

First, can you tell me if this happens every time you open the app, or just occasionally? Also, have you tried quitting the app completely (Command + Q) and then reopening it?

In the meantime, here are some steps to try that often resolve a white screen issue in apps on macOS 10.15.7:

1. Force Quit and Reopen Hudl:
- Press Command + Option + Esc to bring up the Force Quit window.
- Select Hudl if it’s listed and click Force Quit.
- Relaunch the app.

2. Restart Your Mac:
- Sometimes a fresh start clears up app glitches.

3. Clear Hudl App Cache/Data:
- Though macOS apps don’t always have simple cache clearing like browsers, you can try deleting Hudl’s app cache.
- Open Finder, press Command + Shift + G, and enter: ~/Library/Caches/
- Look for any folders related to Hudl and move them to Trash.
- Relaunch the app.

4. Check for App Updates:
- Open the Mac App Store, go to Updates, and see if Hudl has a new version available.
- If yes, update it.

5. Reinstall the Hudl App:
- Delete Hudl by dragging it from Applications to Trash.
- Download the latest version from the official Hudl website or Mac App Store and install it again.

Because this is a white screen issue, it could also be related to a temporary app rendering problem or corrupted data.

If you’ve tried these or if the issue persists, let me know any specific changes you made recently (like OS updates, network changes), and I can guide you through deeper troubleshooting.

Are you able to try these steps? I’m here to help as you go through them!

Actually I’m working with an ipad

Thanks for letting me know you’re using an iPad! That helps me tailor the support better.

Seeing a white screen when launching the Hudl app on your iPad could point to a few possible things such as a temporary app glitch, outdated app version, or possibly storage issues on the device.

Let’s try these steps on your iPad:

1. Force Close and Relaunch the Hudl App
- Double-click the Home button (or swipe up from the bottom if your iPad doesn’t have one) to bring up the app switcher.
- Swipe the Hudl app off the top of the screen to close it completely.
- Open the Hudl app again.

2. Check for App Updates
- Open the App Store, tap your profile icon at the top right, and scroll down to see if Hudl has updates available.
- If yes, update it.

3. Restart Your iPad
- Press and hold the power button, then slide to power off.
- Turn it back on and try Hudl again.

4. Check Available Storage
- Go to Settings > General > iPad Storage.
- Ensure you have enough free space, as low storage can cause app loading issues. You can remove unused apps or clear storage if needed2.

5. Reinstall the Hudl App
- Touch and hold the Hudl app icon on your home screen, tap "Remove App," then "Delete App."
- Go to the App Store and reinstall Hudl freshly1.

6. Check iPadOS Version
- Sometimes app compatibility issues pop up if your iPad's software is outdated.
- Go to Settings > General > Software Update to check if you have the latest iPadOS.

If after trying these steps the issue persists, do you also notice if this problem occurs only on Wi-Fi or cellular, or both? Sometimes network issues can cause app load problems. Also, have you recently changed any settings or installed any other apps?

Let me know how these steps go! I’m here to help you get Hudl working smoothly again.
