Steps to reproduce the problem:
1. From Chrome on Pixelbook go to https://www.icloud.com/
2. Log in to your iCloud account
3. Go to Notes
4. Try to edit an existing Note

What is the expected behavior?
You should be able to edit an existing Note.  I have tried similar tasks when accessing my iCloud account from browsers on Windows 10 and from Ubuntu.  In both cases I was able to edit an existing Note stored in my iCloud account.

What went wrong?
The system doesn't respond when you try to edit an existing Note.  It doesn't give an error or warning message; it just doesn't let you edit an existing Note

Does it occur on multiple sites: No

Is it a problem with a plugin? No 

Did this work before? No 

Does this work in other browsers? No
 In other browsers I have tried in chromeOS I have gotten a message saying that I can't even connect to iCloud because that browser is not supported.

In order to duplicate this bug, the software engineer doing the investigation would have to have an iCloud account and have created Notes in iCloud using a Mac or an iOS device.
