Heya! I hope you're doing well. Unfortunately, yes, we're aware of this situation where the milestones certificates for certain milestones are not showing up, and even If they're showing, their dates are not accurate. They will keep changing the milestone dates to the current date.
Our engineers are still working on this issue as we speak. You can rest assured about it. Once again, we apologise for the inconvenience it caused you due to this.
