® symbol is a different color on mobile than it is on desktop

On our homepage we have a phrase that is a registered trademark "Welcome to Our Journaling For The Health Of It Store!", so we use the registered trademark symbol in the text. The text is all white, including the symbol when viewing on a desktop, but when viewing on a mobile device all the text is white and the symbol is dark. I am not sure why this is different on mobile versus desktop.

I found the issue...it was self-inflicted.

I had copied the text and pasted it in and the symbol "looked" right, but when it was translated it lost the color. I re-entered the symbol using the Alt+0174 and it seems to have corrected the issue
