Incomplete submission in Aggregate

Thank you for this update,
But please, I just open my aggregate(v1.7.1) this morning (12.2.2019) hoping to export the forms that were sent the day before (11.2.2019) from my enumerators using (ODK v1.18.2.) But it appears to me as "incomplete submission" whiles notifying me the new update available.(v2.0)
I am therefore asking if I update the aggregate version to the v2.0, will get those submissions from my enumerators.
