hey @jonathan_ada tried that but it says Error: The installed managed class HubSpot_Inc.HubSpotController is not visible. Looked up the error message and it said it could be version missmatch on the apex. So tried to match it with the current working one (saleforce version 20) still nothing.
Adding Hubspot integration 3.0 to it as well.
Still nothing.
Reinstalled Hubspot last month to the latest version of the Salesforce addon, running winter 19 so all up to date here.
