Insufficient permissions error with email_campaign_summaries despite having correct permissions

I am able to successfully get data from the "/emails" endpoint, but not the "/reports/summary_reports/email_campaign_summaries" or "/contacts" endpoints.

According to the scopes table (https://developer.constantcontact.com/api_guide/scopes.html#:~:text=Available%20Scopes-,Scopes%20Required%20by%20V3%20API%20Routes,-Add%20Scopes), emails and reports are both under the campaign_data scope, so it isn't clear why one is working and the other isn't.

Additionally, I have checked my permissions using the permissions endpoint and I have:

campaign:read, :list, :write, :content:write, :copy, :create

and contacts:lists:read

All of my code/calls were working find before they changed the authorization method, so i've just had to create a new application and have updated my code and method for OAUth2.0 and successfully received my tokens (as evidenced by successfull pull from "/emails" endpoint).
