Why can’t I change text color in Markup on my iPhone 13 Pro Max?

I figured out how to change it. 

1-Add text

2-Double tap the text and  select all the text. 

3-Select “Format”

4-Select “More”

5-Select the color circle

6-Tap the screen to leave the color selection screen. 

7-While the Format menu is showing, single tap the text you want to edit. The other text edit bubble will appear. 

8-Select Aa 

9-Select your color

I also have been experiencing this since the latest update.

Same issues here. Had a 12 Pro, updated to iOS 18, immediately noticed that changing text color in markup wouldn’t work, almost as if the color screen was force closing. It fixed itself for a couple days, then the same issue came back. My husband has a 14 Pro, my son has a 14, and their markup works just fine. I just upgraded to a 16 Pro since I was eligible for an upgrade and my 12 Pro became so laggy. I have the same issues with markup with my 16 Pro as I did with my 12 Pro, so it’s not a phone issue. The issue seems very user specific, but I do think it’s an issue with iCloud. I can save a photo to my files, open up the photo within the files app, and markup works just fine. It does not work through the photo app.

Me too, I just made a post about the same thing. I didn’t see your post beforehand
