I tried changing the aspect ratio on a number of different elements but none of them allow me to use anything other than 1:1. I also noticed if I type 1:3 it changes it to 3:1.
Hey @ghanbak, this is a known bug that will be fixed asap on an upcoming update.
Oh and the workaround is to copy the value typed somewhere else into the field, after hitting
cmnd + a in the field.
