I am evaluating ArcGIS for Offline App on .Net.
I have succeeded running DisplayAMap using free Account with default created App Key.
The requirement for a sample code DisplayAnOfflineMapCustom, it must be Pro Account. So I registered using my company's email and got 21 days Free Trial. Upon opening ArcGIS developer site, no API key created on default. Creating a new key results in the same as many has posted the same screenshot. I have tried to follow the "solved" replies but none works.
We are evaluating GIS solution for jungle operation, most of the time no internet, I hope to be able to use ArcGIS, seems to be a glitch somewhere as the tutorial clearly provides link to 60-days Trial Pro Account, to enable this offline map App Key.
