Same issue here with self-enrolled devices...

Same for me,
The Users make the process at the log out, they enter theirs password, filevault is activate with the good key.

But in Jamf pro the key appear with a long string of characters...

Do you fin any solution ?

To me, this looks like the key is encrypted and was escrowed to Jamf Pro without being decrypted. I haven't seen this issue, but would be curious about how you are enabling filevault and escrowing the keys?

I'm also experiencing the same problem. Did anyone have the solution?

Here are my configuration profile settings.
