Hei Paul Stephenson I had the same issue and thought that it was a problem, but no!!! About the Tiles: See this support page: https://support.esri.com/en/technical-article/000013315 Specially this part: " Example: http://tiles.arcgis.com/tiles/<your_org_id>/arcgis/rest/admin/services/<your_service_name>/MapServer Scroll to the bottom of the page to find 'Resources: Jobs' and click on 'Jobs'. This shows the Tile Service Jobs Summary for the service. If all jobs (or the most current job) show as DONE, then the tile processing is complete, despite the percentage displayed in the Manage Tiles dialog. Cause The percentage of tile completion shown in the Manage Tiles dialog is equal to the number of Tiles Published, divided by the number of Total Tiles. If the number of Tiles Published differs from the number of Total Tiles, then there may have been tiles present in the tile package that were blank and did not include any data. When blank tiles are found in a tile package during the publishing process, these tiles are not included in the Published Tiles. This is why the Percent Complete may be less than 100 percent." About the extent: I had a few problems in the begining because they were not displaying. I zoomed to full extent and set for every layer and dataframe "the current display extent". It worked for me Cheers
