I Can’t Approve The Account Access Request. It Says ‘Pending’ And Can’t Be Updated
This article explains why you can’t approve the account access request in the Google Ads.
The process of approving access for linking your Google Ads account and TCS is automatic once you have completed the prompts provided by Google. However, if you control the Google Ads account through an MCC account, only the owner can approve the account access request.
This can be solved by logging directly into the account or asking your client to approve access.
