Hi, I am looking for a supported way in CRM 2016 and above to display a "Please wait while processing .." message while some time-consuming JS script is being executed. I googled the question but I found some code which manipulates the DOM and I am sure that is not supported. If you can point me to some code to analyze and specially how can I call it so the message is hidden after the JS process is complete, I would appreciate it a a lot.
