Incorrect Phone Icon in Sidebar
Since I updated my iPhone to iOS 26.5, the phone sidebar icon is replaced by one that looks like a grid with concentric circles and a big X in it. The glitch appears to be only cosmetic; the sidebar icon still launches the Phone app. The bad icon only appears when light/default coloration is in effect. When the icons are set to dark or clear, the phone icon shows up normally. The phone icon glitch didn't happen prior to iOS 26.5. The head unit is the factory version in a 2025 Toyota Camry LE. No Toyota software updates show as pending.
Below are a couple of photos that illustrate the point. The first shows light icons with the bad phone app icon on the left:

Contrast this with dark icons. (Clear icons work similarly.) The sidebar looks fine here:
I was on a voice/shared screen session with Apple Support. We tried many resets and settings changes, none of which solved the problem. Switching between wired and wireless connections didn't help either. Eventually we got disconnected and were unable to reconnect, so I gave up.
Have any of you experienced this issue? If yes, were you able to fix it? If yes again, how? Admittedly this is a minor issue with a workaround available. Still, it is a mild irritant.
