I changed the image for a file asset. I am sometimes getting the old image and sometimes getting the new image when I use the same URL. It is as if Salesforce servers are out of sync. Does anyone have experience with this problem & how long does it take to resolve?
After a few days this problem resolved itself. It seems like the asset files were likely cached on multiple Salesforce servers & it took time for everything to sync. Salesforce technical support couldn't confirm this but had no other explanation.
