Possible Rating Glitch?

I’ve run into a bug where I can’t seem to rate a seller; the screen flashes gray and shows it loading but seems to be more frozen than thinking. I can move around the app normally but the gray flashing and loading circle were still there.

I’m sad to say that the rating is only because my order was randomly canceled without the seller letting me know why it was canceled, the item had not shipped yet either so I can only assume that something I had said maybe changed the order or that the item I ordered was missing. Nevertheless, I still would like to post a review of my experience. Anybody know a workaround for this?
