I'm having trouble accessing some activities objects from the account object page. I can access some activities but not others. The permissions error became a problem for our organisation yesterday.
I am an admin and have checked my user permissions and permission sets as well as the permission checks in this article https://help.salesforce.com/articleView?id=admin_insufficient_privileges_object.htm&type=5 and all suggest I should have access.
To further confuse things some records that had this problem unexpectedly stopped producing the error and there is no issue accessing the records in salesforce classic. Any help would be much appreciated.
