Unable to send Teams adaptive card to office group members/security groups /DL groups. For single users it is working fine. But it is required to send to 1k+ users, if the loop is introduced I doubt that the flow will successfully run through the loop if it is more users.
Please refer below screenshot.
Error in flow is "No user details with email or UPN 'SampleDistList@nandadev.onmicrosoft.com' were found in Graph."
