P: Restore Full screen crop (iPad)

I still have my old iPad 7 and it has a previous version of Lightroom that still utilizes full screen crop mode. When it was taken away, i figured it would come back in a future update as a 'new feature'. The mobile app is the very reason I started using Adobe products. Since the removal of full screen crop, I've had to spend upwards of 5-10 minutes, sometimes, trying to crop my images properly. 

Honestly, I don't know why I have to request such a simple feature that we already had while, instead, getting magic wands that do nothing for professionals. If this is too difficult of a task, could you at least completely black out the shadowed edges AND remove the thick white corners?
