Resolve #1186

I am not sure if the OK icon takes too much space. I understand it follows the waiting animation style but to me it looks too large for the OK icon and moves the important content further down.

I was more thinking in a summary similar as in the create offer review screen:

But I am aware of the limited space restrictions, so not recommending to apply that screen to here.
But by not using MaterialTextField fields we would be more flexible with design and space.

I was more thinking in a summary similar as in the create offer review screen:

I wasn't aware that you were considering a complete redesign of this screen. I am reviewing the entire trade's UI experience and will redo this final screen with your input in mind.
