I could not fuel the amount that the app asked me to?

It can be quite common for the tank to appear to be full and then while you wait a moment, you can still fuel several more liters. This is because the air is not able to get out of the tank fast enough. In addition, when the application adds the consumption from the nearest fueling station back to the home harbor, which is just a future consumption, it may also seem that the tank has not been able to accommodate the amount the application has told you to fuel if the tank has been quite full when arriving to the boat. That’s why we also have this fueling balance process, next time you can balance out your fueling balance and fuel a little more.
