Hello. The past couple weeks I have been using Urban through a trial, and yesterday when my company officially purchased both GIS Professional Basic & ArcGIS Urban Suite licenses I am now unable to open an Urban Model I had previously been working on in my trial period. Every time I attempt to open my model I get the following message:

Additionally, I am also unable to create a new Urban Model from a template or from scratch.
My ArcGIS online account user is a GIS Professional Basic with the Administrator role and has the ArcGIS Urban Suite add-on license assigned. I have also tried clearing the browser cache, updated the browser, tried a different browser, and tried a different computer.
If anyone has encountered this issue or potentially has a solution please let me know!
