my expectation group.readwrite.all
inherited app-only directory.readwrite.all
, task.readwrite
should able see tasks , plans.
is there required permission or setting we’ve missed?
retrieval of tasks/plans not supported in service-only (app-only) context. please use user delegation context (app+user) instead.
