I've published a simple style from Pro to ArcGIS Online for testing. It has just one point symbol created from a standard shape marker in Pro symbology. I added the style to a Group and made that group the default 2D web style group in my organization's settings.
I added a point layer to a new map in Map Viewer (new, not Classic) and went to the Style settings, and the uploaded style was listed. However, when I try to load its symbols, the interface just spins and spins. Screenshot attached.
Not sure what I am doing wrong.
I am following the guidance in this blog post.
Solved! Go to Solution.
The issue was with the style file having some unsupported characters and Pro was not flagging or removing them on publishing time which caused broken resources in the web style. If you can update the the key field in Pro on the symbol to remove the illegal characters and republishing will fix the issue.
Looks like I can repro the issue. It looks to be localized to the symbol styler failing to load a gallery with a shape marker symbol in it but if you use a picture marker symbol the gallery loads without issue.
Will changing the default web style group under org settings add to available symbology options or will doing so remove existing default esri symbol sets available in map viewer?
