Screen capture Markup won’t save. [iPadOS 14.7.1]

Pretty simple:

• use iPad on any app or navigate anywhere
• take a screen capture (I use a Pencil swipe from the bottom left corner inwards)
• do some annotations on it, crop, frame, etc
• Save To Photos.

The result on the photos library is the full screen original screen capture with none of the edits or markup annotations.

Extra info:

Have seen other similar support threads on this but all of them from many months or years ago, either it was fixed and it came back or it was never fixed to begin with.

There was the suggestion about doing a rotate edit of the canvas and back before annotating but that option doesn’t appear, that seems to be only useful if annotating an already existing file on the Photo’s app and not directly from a screenshot.

Any help greatly appreciated.
