In the event they are incurred, we will always pass on any additional fees from an operator. We never add additional charges to operators fees. The parameters of the overstay penalty are always set by the operator.
Time based and connection fees are indicated before a charge in the location overview and connector confirmation screen.
Users on version 2.18.1 or later can also get overstay fee warnings with our status updates feature that is available with a Light Boost subscription. Find out more about what's included in Boosts here.
