Refer to https://cfl.re/3VUQyyL for assistance. The zone you are trying to upgrade is marked as Do Not Upgrade. (Code: 1315)

Could you provide a screenshot of the error that is displaying ?

I see my colleague replied on 3262202 @metrin92 is everything working ok now? Let us know if not or any other issue.
