Unable to take free trial o Microsoft Syntex

For the past two days, I have been attempting to access a free trial of Microsoft Syntex, but every time I encountered an error message stating, "Something went wrong, your product isn't available." During my research, I came across several blog posts mentioning the "Syntex Per-User License Notice end of Sale." I would like to know if Microsoft has made any official announcements regarding this change. Could you please provide me with the link to Microsoft's announcement regarding the end of per-user licensing for Syntex?
