Kopibarka Hello!
If you previously registered units in one account, and then deleted them from there and registered in another, then you will not be able to receive the data that was received before the units were deleted, because along with the deletion of the unit, you delete all information associated with it.
If in the old accounts from which the units were deleted, there were no units and other relevant data left, then they could be deleted automatically due to inactivity.
