Nested Resources don't seem to work about landlord

Because it's not required.
If the parent is Tenant Scoped, and the child is referenced on a foreign key, the Scope is not required.

As the child is anyways bound directly to the parent (Account), and you'd "always" access the (Template) from the Account, through the relationship.

If you want the child to also be tenant-scoped, you'd need to use the BelongsToTenant trait on the Template-model as well, and make sure the Template-model is not being booted before the Account model is booted. But as mentioned before, scoping a child, is not strictly required if the parent is scoped.
