Adjustment of Status - I-485

Hi for those who are and the same boat please comment here on your current update. I have received my recent update. I was approved for my green card 6 months ago and got my green card couple of days after the approval , and on July 3 it’s system update to “my case is ready to be scheduled for an interview” and now I got another update saying the following “On July 8, 2019, we cancelled your interview for your Form I-485, Application to Register Permanent Residence or Adjust Status, Receipt Number MSC1xxxxxxx,and mailed you a cancellation notice. We will notify you by mail if the appointment is rescheduled, a decision is made, or if we need something from you. Please follow any instructions in the notice. If you do not receive your notice by August 7” has anyone got the same update...I know I was told by the uscis it was a system issue, but I am wondering who has their case change to the cancellation notice. Thank you in advance.
