iOS Safari extension cannot connect to app

Recently the Safari extension on my iPhone stopped working. I am unable to sign in with my master password or Face ID, which both work just fine in the 1Password app. I also get an error message saying it cannot connect to the app. I've tried all of the troubleshooting steps I could find, including:

• Clearing the browser cache
• Force quitting both apps and signing into the 1Password app before trying the extension
• Uninstalling and reinstalling 1Password
• Restarting my iPhone
• Toggling various 1Password security settings
• Disabling and re-enabling the extension

I am on the latest version of the 1Password app and iOS 26.4 Public Beta. Any ideas how I can get this to work again? Is it an issue with the iOS beta version?

Thanks!
