Hi @Anonymous ,
Could you please show more details about the formula you typed within the Items property of the DataCardValue4?
Do you set the Items property of the DataCardValue4 to AzureAD.GetGroupMembers('group id').value function?
Regarding the issue that you mentioned, I think this issue is related to the formula you typed within the DefaultSelectedItems property of the DataCardValue4. If the Items property of the DataCardValue4 is set to AzureAD.GetGroupMembers('group id').value function, please try the following workaround:
Set the DefaultSelectedItems property of the DataCardValue4 to following:
LookUp(
AzureAD.GetGroupMembers("xxxxxxxx-2d32-xxxx-807c-73550848af7b").value,
mail = ThisItem.PersonField.Email // PersonField represents the Person type column in your SP List
)
Note: The 'xxxxxxxx-2d32-xxxx-807c-73550848af7b' represents the group id in my AAD, please replace it with your own group id.
Please try above solution, check if the issue is solved.
Regards,
