I am having a problem obtaining consistent switching with your pro plugin. I have recently added Total Cache to my site and I test the site using a Kindle HDX that allows me to request either a desktop or mobile view. I have added amts_mobile_theme to the rejected cookies box as per your instructions. The themes I’m using are Graphene and Graphene Neo. Just when I think everything is working correctly, the Kindle will not display the requested theme (i.e.- I get the desktop when requesting the mobile.) If I clear the cache at the WP site, it will work again. This doesn’t happen all the time (maybe once or twice a day) so I haven’t isolated what is happening. Do you have any suggestions?
I also have a user agent switch on my desktop and will try switching views the next time this happens.
