1Password stops working in Chrome Canary #

First:

• make sure everything is up to date (Chrome, 1Password Desktop, 1Password Mini)
• restart your browser and even perhaps your computer

To resolve this issue you have to copy

~/Library/Application Support/Google/Chrome/NativeMessagingHosts/2bua8c4s2c.com.agilebits.1password.json

to (maybe you have to create the folder as well since Canary doesn't create it by default):

~/Library/Application Support/Google/Chrome Canary/NativeMessagingHosts/2bua8c4s2c.com.agilebits.1password.json

Reason: Chrome Canary installs its NativeMessaging JSON file into a different location than Chrome.
