Student Submission is rotated for annotation, but then returns to unrotated position

Community Member

All of a sudden last night, I began to see student work go back to pre-rotated position, but my annotations stayed upright - making this very confusing.  I have done this all year with no problems, so I am not sure what changed last night to make this do this!!  I have to rotate student work often before annotating.  Now the annotation feature is worthless for them.  Was there some update that caused this?  Is there some setting I need to do to make the work lock into position?  I really would appreciate some help with this.
