I am so disappointed with this. I’ve been asking for this feature over the last few releases. All I wanted was a solid color background, which I find helpful as a visual cue that I’m texting the right person. Instead, they implement this abomination, without the ability to use a solid-colored background. I wound up creating full color screen images and importing them as a photo background. Sheesh.
However, the backgrounds do not work well. They often disappear, and bread replying from the notification.
