Since an automatic update to yesterday the Chrome extension is completely non-functional. Opening 1Password mini while Chrome is the front application prompts to install the Chrome extension, which is already installed. Removing and reinstalling the Chrome extension has no effect. This appears to have been mentioned several times on the Chrome extension page (below), but I didn't see anything about it on the forum yet. Hopefully this will be resolved very soon!!
