XF 1.2 Some buttons show gradient on mobile only?

[cmeinck]

Here's an odd issue. I've removed all the gradients in the Styles > Buttons section. On the desktop, it looks as intended. When browsing on a phone, the gradients still appear in some places. Not a cache issue, because some of the phones tested had yet to see the updated site.

Check for responsive specific CSS.

Resize your desktop browser and use an inspection tool to check the classes being applied.
