Automating B2B invitations for users with Education plan licenses

We notice that for guest from partner tenants who have an educational license (A1, A3, A5), a Sharepoint profile is not being automatically created once the guest account is successfully invited on the AAD tenant.
Therefore we're unable to to successfully complete  our bulk operations and replicate the guest users SP properties in the partner tenant.
And we cannot expect this large volume of users (25K+) to explictly redeem the invite or login to the portal so that the SP profile is provisioned.

This is not the case if the guest user is linked to other types of business or E licenses. Automation works end to end as the SP profile is automatically created by MS.
Is this a known limitation imposed by Microsoft on Education Plan licensed users?
