I have a custom master page in SharePoint Online. I ran into an issue while customizing the Office 365 Suite Bar. The code I have worked well using my account as a first release customer, but does not work for non-first release users. It seems I need to use different logic in my code depending on if the user has first release. Is this possible to do in JavaScript in SPO? I checked _spPageContextInfo, but all the version information is the same
