GLS is newly integrated to Shisptation which is a good thing for us. However, due to the high lever of parcels we are shipping using this carrier, there need to be an "End of day form" available for this carrier, as is it for all (or almost all) the other carriers. After talking to GLS, they say they do not understand why it hasn't been developed at the same time as the integration, since it is a necessary step when shipping using their service. Please have this resolved ASAP, as right now the message error "The carrier does not support creating manifest. (404, ad50a618-3dd4-4a2e-8b0e-3f7a3096c941)"
