I work on a LOT of Hubspot sites and I encounter this problem often with child themes. Appending
?hsDebug=true&hsCacheBuster=4878
to the URL works often, but problem is… that isn’t the real world. A user isn’t going to visit that and there’s very little transparency on the CDN updates, Hubspot generated CSS, etc. I have waited over 72 hours to see minor CSS updates take effect. It would be really helpful to have more control or information over this subject.
This “hack” seems to work in certain situations - How can I clear the server cache?
