"Failed to display the raster layer as Classify" in Arcpro 2.3.1, but works in ArcMap

[MollyBarth]

Hi, 

I am trying to symbolize a USGS DEM elevation raster into 2 classes: Values above 100 and values below 100.  

In ArcMap, I have no trouble doing this.  I open the raster properties and click "Classified".  I answer "yes" to the question about computing a histogram:

No problem there.

However if I try to do this in ArcPro 2.3.1 on the same exact raster, it won't work 

What am I doing wrong?

Thank you for the help!

Hello, I've also tried the steps above but I still get the error message "Failed to display the raster layer as Classify".  Are there any other solutions available?

Thank you.

upping the Maximum number of unique values(all the way to 100 million!)  worked for me.   i originally stopped at 10 million thinking that was already ridiculous and still receiving the error.  but 100 million worked for me..
