This happened to me as well on a test machine.

Do you know if the test machine had find my on?

The 2 machines we did were ours in the IT department which have admin accs and findmy on and they both rotated the filevault key.

I've since done 2 more machines that don't have findmy on and they didn't rotate the filevault key and were fine. Trying to understand if it's a 15.0 bug for some machines or a findmy/activation lock issue with Apple rotating filevault key.

Hello, 

I just noticed the same thing, tested on an admin managed device with an apple ID configured but findmy is disabled. The filevault key rotated but was not uploaded to JAMF.

So upgrading to Sequoia wll be postponed for now...

Any news fro JAMF or Apple why the key rotates?

Same Problem here - though I'll need to figure out if the user activated Find My. Any updates on that topic?

I received the following statement from Jamf support:

This issue is a Product Issue (PI120801) that our team is working to resolve. I have attached the case to the Product Issue and you will receive an email once it is resolved.

Please let me know what they come back with.
We're holding off upgrading until we're 100% confident it's more seamless.
