Hi,
I tried to contact the Help Support Team by email but did not get a response. I just want to let them know that it looks like Prey forgot to update their ‘Apple Worldwide Developer Relations Certification Authority’ certificate. This Apple certificate expired on March 7th, 2023.
Unless Prey leverages the latest Apple certificate, new users won’t be able to enroll their iOs devices (APNS). I am attaching a picture showing the failed process.
