Hi @loldenburg,
Not at all .
I guess this is a similar topic:
The verified/partner connector (compared to the previous unverified one) ties the data source to your Google account. Meaning 1 pair of credentials per 1 Google account.
We are currently working on a feature that will allow you to add other Piwik PRO accounts/instances to your Google account when you create the data source. If you’d like to test it before the release, I’d be happy to send you the developer version of the connector once we are done testing.
For now it’s best to use the 1.3.0 version for other client accounts.
