Caching issue?

I have since re-installed the 1password extension, which felt quite drastic to me.

I just did a test:
(main window) logged into my.1password.com
enabled 1password extension for incognito windows in chrome://extensions (click "Details" button)

opened incognito window, navigated to my.1password.com
change password on my.1password.com main window to some nonsense

Reload my.1password.com page in incognito window
changes were reflected.

Separately.. I'll want to highlight the egregiousness of discovering that reinstalling the extension fixed any issues.

The extension was always failing to save things from inside a webpage. New account/new website, generate password (works), then click "Save in 1password" and it would open a full modal, and... it would ALWAYS fail, showing basically "Failed to save item" in red text at the bottom of the modal.

Likely, SOMEBODY at 1password encountered this bug during some testing, manual or automated, but unfortunately doesn't have much experience around caching bugs. Instead of really pondering why this bug appeared, they simply reinstalled the extension. Little did they realize, it was a caching bug. Yes, reinstalling the extension fixed the issue. BUT it's a real issue. Now likely EVERYBODY needs to reinstall the extension, lest you figure out how to do some sort of crazy cache bust...
