You might not be aware, I wasn't in the beginning, that some of the Listia mobile apps cannot see the update section. The ios app CAN on an ipad but the Android one CANNOT. Alas I am using the Android one this morning.
Another thing: Neither the Android or ios apps can see a GIN option...
Lastly, it is a good practice as a seller to post a comment that updated info was added above. . that way at least folks like me will know that they are missing something.
