Sharing with groups: no email sent

At this moment we are working at the automatisation of users in different groups (according to functions and organizational units).

We are doing this with mailenabled security groups in AD, Exchange online and AAD-groups.

Sharing a powerbi-scheme with one of those groups seems to work, but there is a small communication-problem.

When you share a scheme with some users you can send immediately a mail with some explanation to those users. This works good for users, but when you share with one of the groups mentioned above, no mail is received by the members of this group. We did also a trace and cannot find the mail send to the group. If we use the group in Outlook to send an email, the members receive a mail.

Any idea why PowerBi does not send the mail to the group?

Thanks in advance
