If you are finishing a container that was created and opened before the weight tracking update, you will not be prompted to enter a final container weight. This is because the container was created before the update, meaning no starting weight was recorded.
If the container balance is not zero, an adjustment will be necessary—either up or down to bring the remaining balance to This discrepancy may be due to factors such as manufacturer underfill, manufacturer overfill, or other discrepancies.
