HAHA, I just realized what I did. My image was black and I assumed it would just change the color, but instead, it's more of an overlay. You can't change the color of black! Mystery sold! A little embarrassing, but solved! Thanks @Aidan-Oxley!

I’ve been having this same problem with no help. I’ve logged out and in, deleted app and redownloaded. Still has the same error code. Will the “Viewer” app be fixed, so I can airdrop and test my HyperPad games on my phone again?

Think I got it. It's not work on the PNG file, but it works on the jpeg files.

Yes, the behavior is "on" and the opacity is all the way up. Not sure what else it could possibly be.

No luck, I have the same behavior setup in another project that works but not in this new one. In my object, I only have one behavior, "set color". I set it to "linear", the color green, and "0" for an instant change when I push play. Nothing happens. Am I missing something?

The "Set Color" behavior is not operational in a new project. I checked an older project and it works there. Anyone having the same issue?
