I have experienced data loss with Apple and the support team telling me the knew about it but could not pinpoint the issue.

I had entries disappearing from my Contacts (iCloud). The customer support asked for me to get back when I notice the issue so they could get logs to debug. My best friend contact entry disappeared overnight. I called the representative the day of and told him that the contact disappeared between yesterday night and today morning. His answer was that I needed to pinpoint more accurately when the contact disappeared, because iPhone generates a lot of logs and and engineers don’t have time to go through them. Ah!

Needless to say I stopped storing my contacts with iCloud and my trust eroded. “Funny enough” I also had issues with my Health data, years of it disappeared. Support could not do anything. The data magically came back a month later or so.
