Why is my iPhone's Calendar app icon black and not red?

My iPhone's Calendar app icon changed to black and white two days ago. it's not due to dark setting or tint setting. I rebooted my phone and it stayed the same. My iPhone is 16 Pro Max with the latest version of IOS 18.4.1. how can I change it back to the normal red and white?

Can I switch back to black dots on Calendar app? I updated my iPhone last night to ios 18.11 and all of my appointments in the calendar used to show black dots (easy to see) and now the black dots were replaced with small color dots or dashes (Very difficult to see). Is there a way to switch back to black dots? [Re-Titled by Moderator]

Calendar not showing up on iPhone SE Several people have reported this. It is on the phone- I see it in App Library and in App Store it says OPEN. Still, the icon does not show up on Home Screen. How do I get it there? Very frustrating that I can’t access it.

Iphone icon size My calendar was stuck and, instead of closing it to fix that issue, I removed it from my homescreen. When I went to the app library and put the calendar back on my home screen, the icon came back 4X the size of all the others. How do I return it to the normal icon size?
