I have uploaded a raster tile layer and added it into a webmap. The problem appears when I zoom in: some parts (tiles) of the image dissapear. This is the link of the webmap with the tile layer: https://urjc-royal-sites.maps.arcgis.com/apps/mapviewer/index.html?webmap=5040b00d9f5b43e6994ff335f1...
Someone knows why this happens?
Thank you in advance!
Could you check (Show Details) if the tile building is 100% completed for all the scale levels?
I think there are issues with the tiles beyond level 14.
You might want to have a look at the tile package that you created as well.
