Folks over the past week or so, we've been seeing these javascript errors start appearing on our sandbox instances of CRM Online.
The error appears to originate in the JsProvider.ashx and cdnavailabilityworker.js files which are internal to the CRM.
My question is what causes these errors? Are these a result of Microsoft updating our CRM Online site and introducing a bug or is it something we've done on our end? It seems to be on Microsoft's side since we have an out of box instance (organization) without any customizations that we created a month or so ago which has the same errors. The issue shows up in Chrome and IE and after clearing the browser cache.
Is this a known issue? Does this require a support incident for MS to resolve?
