Black box around raster layer retreieved from Mapbox in ArcGIS online

Question

I manage a mapping system for the Pine Ridge Reservation in South Dakota and am trying to retrieve a raster layer but I keep getting this expanding black background/box.

When I open the mbtiles file in Qgis it looks fine but when I retrieve the file through ArcGIS either as a WMTS layer OR the Mapbox instructions for pulling layers into ArcGIS online of "Add > Add Layer from Web > A Tile Layer" there's black box around it that increases in size as you zoom-out.

See image.

Here's some relevant details about my data:

• The original file was converted from Geotiff to Mbtiles format in TileOven (active Linux fork of TileMill) and then uploaded to Mapbox and styled in map box studio.
• This is not a no-data border in the original geotiff. The original geotiff has only a tiny border that I'm not concerned about concealing.
• The original geotiff was created using GDAL processing tools in Qgis
• To convert the file from geotiff to Mbtiles in TileMill I used these instructions https://www.youtube.com/watch?v=05Et84xIgls
• I made certain I set extends in TileMill and ArcGIS online.
• I also tried uploading the Geotiff directly to ArcGIS online and the same thing happens.
  • I'm using TileOven, QGIS 2.18 on Kubuntu 18.04 with KDE Plasma 5.12.6 Software

Here's the ArcGIS Online integration URL provided by MapBox https://api.mapbox.com/styles/v1/dbartecchi/cjlgwhz4704j02rldjapn5wzc/tiles/256/{level}/{col}/{row}@2x?access_token=pk.eyJ1IjoiZGJhcnRlY2NoaSIsImEiOiJPV0cyMW1NIn0.D5p-ioo0SzDujMVD77ZQIg

Here's the Mbtiles file opened in QGIS 2.18 looking exactly how it should look.

Ok, I never found a fix for this issue but I did find a workaround using MapTiler Desktop which converts a geotiff into a tile layer (that looked much cleaner that the MBtiles created by TileOven). MapTiler allows you to export as a folder that you can upload to your own website and which contains all the files you need to serve your own files via WMTS or a number of other formats (including embed codes).
