KEY: stronger indication if you have successfully copied username or password on iOS

Please make it more visually clear or stronger indicated if you have successfully copied the username and or password from KEY on iOS. I find myself going back and forth, because i clicked on copy, but either I'm clumsy or back at pressing precisely.

Perhaps it could change colour or hue slightly. Or perhaps it could change to copied for a a few sec etc. I don't know. But anything would help.
