I created a hillshade raster that I would like to use in the field with Field Maps on my phone. When I go to share this raster from ArcGIS Pro as a web tile layer, I'm having problems with the raster being capped at a relatively poor level-of-detail. As the screenshot shows, the highest the slider goes to is level 18 (1:4,252) for maximum resolution.

I cannot adjust the slider and I cannot change the tiling scheme from "Auto-suggest".

If I use Field Maps with this tile layer as the basemap, I run into the overzoom problem where the map disappears at a close enough zoom level. I've solved this in the past by adjusting values in the JSON data, but it doesn't solve the problem of not having the more-detailed tile layer, it just allows one to zoom into a pixelated lower-res version of their basemap.

Is there a way to actually publish the tile layer at a level of detail that matches what I see in ArcGIS Pro? I included the second screenshot to show the level of detail that I can see at 1:1000. Still pretty good. I've seen ESRI support documents that say other tiling schemes go up to 24 levels-of-detail, but I can't change my tiling scheme for whatever reason.

I am using ArcGIS Pro 3.1, AGOL, and Field Maps.

In my experience, this issue pertains directly to the coordinate system the map is projected on.

Esri is typically using WGS 1984 Web Mercator, which is the default for ArcGIS online. According to Esri, the level of detail is automatically calculated based primarily on your target coordinate system. You are using a localized NAD1983 2011 projection, which I also am.

I found that with the local NAD1983 2011 projection, I cannot gain greater detail than 18 - 1:4106. I also tested using more compressed imagery rasters, and even just not having the imagery file at all; this does not make a difference. However, if you use the NAD1983 UTM Zone projection of your state, then the permitted detail can down up to level 18 - 1:1126.

However, if you use the WGS1984 Web Mercator projection, you can get detail up to level 23, as Esri advertises. I was unable to find a solution, but I hope this clarifies the issue.
