Hi steveraven,
Sorry to hear about the trouble you’re having. It sounds like there may be a conflict with the desktop theme, if the settings in the Customizer aren’t saving. To verify, very briefly activate a default theme like the Twenty Fifteen or Twenty Sixteen theme. If the issue goes away after activating a default theme, it is likely that the other desktop theme is loading its scripts outside of its own admin pages. Which is bad practice according to WordPress.
If the issue persists, you may want to check if one of the active plugins in WordPress is conflicting by deactivating them one at a time in the Plugins page in WordPress and see if you find a culprit. You can start with the plugins you suspect may be causing the issue, if you have a large number of active plugins.
Let us know if that works for you or if you have further questions. Thank you for the feedback. We’d love to have a chance to earn a 5-star review from you!
Regards,
Emilio Rivera
