Pro has new tab called Content Builder with colors for links, buttons, etc. For some bizarre reason, after upgrading to 1.2.3, and changing a theme option in another tab (NOT Content Builder)…the default button colors and button styles in Content Builder overrode the existing color settings in the Buttons tab (but oddly not the link colors in the Typography tab) sitewide.
I basically had to go into Content Builder and copy the same settings into there as is in the Typography and Buttons tabs. Why does this Content Builder tab exist in Pro? It’s not a separate plugin and everything in it is already covered in other theme options tabs. Strange.
