We had people taking photos for profile at work.  Microsoft shop, so active directory / exchange etc.  If you took a photo with an apple device, it would always get the image sideways, but androids would not.  It looked like apples handle the rotation differently (e.g. they save the image whichever way, but keep exif data but android rotate the image to be 'up' and save it)

If you're using windows, IrfanView has command line commands for rotating (and much much more) in the i_options.txt file.  That was how we fixed the issue

I was also going to say what CW was but I see you figured that out :)  And CCW could be Counter ClockWise if using the American version.
