> Apps built on Zendesk Apps Framework v1 are being removed in October 2019. Click the 'V1 Apps' tab below to see which apps require your attention
The Carbon Copier app is not listed in the "V1 Apps" tab, but that might be simply because it doesn't list *any* Framework version in its "General Settings" tab. Does that provide a clue?
I've also sent a message to the app developer to ask about this.
