Hello ArcGIS Online world.
I have been hosting a vector tile package and its subsequent hosted tile layer for 4-5 months now, and as of Today (August 21, 2018), it is now rendering with a line delineating the boundary of each tile for that zoom level (See attached two screen shots). These rectangular white shapes are not of any relevant coordinate system, are not a layer within the package, and do not exist in the .mxd the tile package was generated from, not to mention that they were non-existent prior to today. These lines appear in new map views pulled directly from the hosted layer, as well as my months old web apps and web maps.
Has anyone had this happen to them before? Any suggested solutions?
Thank you in advance
