No colour palette available to use when using Markup
We have a strange issue with one of our 2 new iPhone 16s. One, a 16 with 256gb memory works absolutely fine, but a 512gb 16 Plus will not display more than a brief flash of the colour palette when trying to manipulate a shape in a photo. You can add a shape, but as soon as you try to change the fill colour the colour palette appears for a nanosecond on the screen and then disappears. This means you cannot carry out any markup actions to your photos.
Both phones are using the latest software, IOS 18.0.1
Anyone got any ideas?
