Fonts do not change in mobile

Hi

I am using the WPNotes plugin and as such it is working. I am using the OceanWP theme and elementor page builder. I chose a font in WPNotes and it showed on my mobile and laptop. But later I changed the font. The updated font reflects correctly in the laptop (and also in the page in elementor in desktop, tablet and mobile modes) but not in my smartphone. I have tried it many times, cleared cache, etc. but nothing works. Can someone please help me in resolving this problem? The fonts should appear the same in all the gadgets. I am using the google chrome in both my laptop and also my mobile.

Thanks
