Contact photos are disappearing across all of my devices. Also, some contact fields are garbled
My contact photos are regularly disappearing from all of my contacts across all of my devices. If I add a contact photo to any contact, it will revert back to gray initials within about a day or so.
Also, occasionally some of my contacts will have a field with garbled text. For example, right now one of my contacts phone number's is (xxx) xxx-xxxxIMPP;X-SERVICE-TYPE=qq;TYPE=OTHER:x-apple: (I x'd out the number itself for privacy).
Another of my contacts phone number's is (xxx) xxx-xxxxINITIALS:G.D.INITIALS:G.D.INITIALS:G.D.INITIALS:G.D.INITIALS:G.D.INITIALS:G.D.INITIALS:G.D.INITIALS:G.D.INITIALS:G.D.
And another one looks like this: (xxx) xxx-xxxxX-ABShowAs:COMPANY
The country field on my own contact card looks like this: United Statesitem5.X-ABADR:us. I've fixed it several times and it keeps changing back. Also, my home address on my contact card is using the generic "address" label instead of the "home" label. If I'm driving and I ask Siri to navigate home, she says I don't have a home address. So I change my address to use the "home" label, and within a few days its changed back to "address".
To be clear, a contact does not need to contain garbled text for its photo to be deleted. 80-90% of my contacts contain no garbled fields at all. But 100% of my contacts will not retain a photo for more than a day or so. I'm mentioning the garbled text simply as another data point of something weird happening with my contacts.
This has been happening for several months and all devices have been restarted since this first began.
I have a 14" M1 MacBook Pro, an iPhone 12 Pro Max, an iPad mini, and an iPad Pro. All devices are on the most current version of macOS / iPadOS / iOS. Contacts are fully in sync across all devices. It does not matter which device I use to edit a contact or add a photo.
