The bar with ratios is nearly always useless and redundant with the ability to resize manually: I would delete it.

It's more difficult to resize with the "angles" because those are moving both vertically and horizontally. In the native app, it was possible to resize only vertically or horizontally, which was more precise and fast.

At the end (not the same issue), sending photos is not asynchronous: you have to wait before the photo is uploaded.
