[Question about multiple selection and proportional resizing.]

Thank you for the info.

I still think there is something that needs to be fixed in the app. The other two methods should work.

[Question about multiple selection and proportional resizing.]

I am trying to figure out how to lock aspect ratio (proportional resizing). The methods that should work aren't. It seems to be a software bug that needs to be fixed.

[Lock aspect ratio]

I have searched this site and read guide in app. I cannot get the lock aspect ratio to work.

1. When I select the lock icon in Transform Studio the shape still free transforms (aspect ratio is not locked).
2. I cannot select "constrain" in the shape menu.
3. Touching screen with finger while dragging shape with pencil does not lock aspect ratio either.

I am using an iPad Pro 1 with Apple Pencil, (IOS 10.3.3, Affinity version 1.6.4). 

Please help
