Annotations Disappearing

Teachers at my school are reporting that when students submit their work either via Kami or Google Classroom, that student annotations are disappearing on the submitted copy. They see students working and annotating on their documents, but once submitted, the annotations disappear. Anyone else having this problem and/or know of a fix for it??

We are having the same issue. Students complete work and nothing shows on the teacher side when turned in.

i had to do annotations yesterday if it happens to me i will let y’all know and we can see if we can figure some thing out
