In ArcGIS Pro, I have configured the popup to grab images using a URL under HTML mode. I have since changed the images at the URL location but the popup window is still displaying the original images. It must be stuck in some kind of cache nether region. I tried clearing the Local cache (Project > Options > Display > "Clear cache") but that must be for databases.
If I paste the URL in a browser it's showing the correct new image. Does anybody know how to flush the popup window of these old URL images?
have you tried restarting your ArcGIS Pro?
