Hi there! I understand your Pencil Notes app isn't updating, and I'd like to help you get that sorted out. Just to clarify, when you say the app isn't updating, do you mean the app itself won't install the latest update from the App Store, or are you referring to your notes or drawings within the app not syncing or refreshing as expected?

Could you also tell me if you see any error messages, and if your internet connection is stable? This info will help me guide you better.

Not updating from Apple

Thanks for clarifying that the Pencil Notes app is not updating from Apple via the Mac App Store. Let's work through some steps specifically for your Mac OS X 10.15.7 system to see if we can resolve this.

1. Check your internet connection: Ensure your Mac is connected to a stable internet network, as updates require internet access.

2. Sign out and back in to the Mac App Store:
- Open the App Store app on your Mac.
- Go to the Store menu and choose Sign Out.
- Then sign back in using your Apple ID.

3. Check for Apple system status: Sometimes the Apple App Store services have temporary outages that prevent downloads or updates. You can check the official status page here: https://www.apple.com/support/systemstatus/

4. Manual check & update:
- Open the App Store and click Updates in the sidebar.
- If you see Pencil Notes listed, click Update. If it is not listed, try searching for Pencil Notes and see if the Update button is present there.

5. Restart your Mac: A restart can often clear up temporary glitches.

6. Check storage space: Make sure your Mac has sufficient free disk space to download and install updates.

7. Reset the Mac App Store cache:
- Open Terminal (through Spotlight Search, press Cmd + Space and type “Terminal”).
- Type the following command and press Enter:
open $TMPDIR../C
- This will open a folder in Finder. Find and delete the folder named com.apple.appstore if present to clear the cache.

8. Update your macOS if possible: Sometimes app updates require the Mac OS to be at a certain version. Your OS X 10.15.7 (Catalina) should still support most apps, but if possible, consider updating to a newer macOS version.

If you have tried any of these already or notice any error messages during the update attempt, please let me know. Also, does the App Store show any specific messages or errors when you try to update Pencil Notes?

Let's start there and I'll guide you through whatever next steps are needed! Are you able to try these and update me on the results?
