Not responsive and unsolved bug

Nice plugin so far but I had to uninstall due to the following issues:

– it is not responsive – latest Google updates will most likely punish your website score for using this plugin

– the setting ‘hide on mobile devices’ is not working properly. Menu is still displayed on iphones and android phones (Samsung Galaxy). It blocks the rest of the pages so they can’t be used properly.

It seems the developer is not willing to address the second issue as it has been stated for over 2 years now and he doesn’t even reply.
