Hi there! I see you're having trouble with the AccuWeather app not opening on your iPad. That can be inconvenient. Could you please tell me a bit more? For example, does the app try to open and then close immediately, or does it not respond at all when you tap it? Also, have you tried any fixes already?

While waiting for your info, I can suggest some general steps that often help with these kinds of issues on iPads:

1. Close and Reopen the App: Double-click the Home button or swipe up from the bottom to view open apps, then swipe the AccuWeather app off the screen to close it completely. Then try opening it again.

2. Restart Your iPad: Sometimes a fresh start helps. Press and hold the power button, then slide to power off. Turn your iPad back on after a minute.

3. Check for Updates: Go to the App Store, tap your profile icon, then check if there is an update available for AccuWeather. If so, update it.

4. Reset App Cache: On iOS devices, you can sometimes fix app issues by going to Settings > AccuWeather and toggling "Reset cached content" if that option is available. Then restart the app.

5. Delete and Reinstall the App: If none of the above work, try deleting AccuWeather (tap and hold app icon until it jiggles, tap the x, confirm), then download it again from the App Store.

Does your iPad have the latest iOS version 15.7 installed? Since you mentioned OS X 10.15.7 that is macOS Catalina; just to confirm the iPad's iOS version as well would help.

Let me know which of these you've tried or if something specific happens when you open the app, and I can guide you further! If needed, I can also check for any recent updates or known issues with the AccuWeather app on iPads2 3.
