site icon shows different laptop and mobile

hi there! need your insight. I was working on site A, then needed to separate site, so made clone A to B. on A there was site logo (dark blue) ,so on site B I changed logo accordingly. (light blue)
now I was testing site B, the new one. on laptop shows correct logo. (light blue) but for mobile, remain dark blue.
of course I clear history and cache on mobile phone etc. on chrome developer mode same result.
can you tell me how to correct, please!

thanks!
