Hello,
I am working on creating thumbnail templates for my organization to use in ArcGIS Online. However, I am having trouble getting the text in the thumbnail to appear nice and crisp. I've tried many different export settings and file types, but none seem to make much of a difference.
Here is an example of some custom thumbnails from an image taken from the recent "What's New in ArcGIS Online" post:

And here is an example of my template - pretty standard design and format. This particular one was made with an ArcGIS Pro layout template, so that whoever makes the thumbnail can easily use the Map Frame element to get the exact capture of the map that they want.

Is there a different setting or "best practice" I can implement to help make my thumbnail a bit sharper?
