Hi, I´m getting an error when trying to delete some of the external users from the business account. The common ground for those who "can´t be deleted" is that there are no information within the fields "Date added" and "Collaborations". I´m also not able to view their details for further diagnostics, as an error message appears there: 

"Apologies, we were unable to load this page. Please refresh the page or try again later."

Could you please advise? I talked about 8 users to be deleted. Thank you for the support. Petr
