I have installed the plugin successfully to use a custom font called recoletta but it is not showing up cirrectly on a few devices, especially I phones. These devices instead, show the content in a serif font. How can I ensure that there is consistency across devices for the font being used?
All the setup looks good to me. However, seems like cache issue for Iphone. I think you are using some sort of cache or minify plugin, can you please purge your cache and try again ? Also some cache plugins have different settings for mobile devices, please make sure to clear those as well.
