ISN Scheduler Loading Error - endless spinning

ISN Scheduler with embedded iframe not loading

Do you use iframes to embed 3rd party applications such as contact forms? Usually they work fine, but some users may experience unusual behavior or a failure to load depending on their browser cookie settings and the way the app is programmed. We recently tracked down a problem with the ISN scheduling app not loading due to 3rd party cookies not being enabled. See video for explanation and fix. https://youtu.be/42fvwjloB2s
