Hi @Anonymous - yes! This has been delivered. You should be able to connect an additional Google Ads account by navigating to your HubSpot Settings (gear icon) -> Marketing -> Ads, and then click 'Connect account' and follow the authorization steps.
Re: Link multiple accounts to Ads add-on - changed to: Delivered
All users with Marketing Hub Professional or Enterprise or the legacy Ads Add-On (sold before 12/3/2018) are now able to connect multiple Facebook Ads and Google Ads accounts to HubSpot. Google Ads accounts must be connected by the same user.
Hi @specksie - we are actively working on the ability to connect multiple Google Ads accounts to HubSpot. We anticipate releasing this functionality in December. At the outset, we will not be able to support the full MCC structure -- you will need to connect each individual Google Ads CID to HubSpot.
Re: Link multiple accounts to Ads add-on - changed to: In Planning
We currently have support for multiple Facebook accounts in a closed beta for Ads Add-on customers. If you are an Ads Add-on customer, you can sign-up here: http://bit.ly/hsadsbeta. This feature will likely be out of beta for all Ads Add-on customers by the end of the month (June 2018).
