Attribute is not selected on mobile default theme, please help

[хамак]

Hello all,

 

i just found very strange issue on my Prestashop 1.6.06 installation - when i try to change the product`s attribute on Chrome/default Internet browser via my mobile phone - nothing is changed and the default attribute is still selected. 

 

For example i want to change color from white to black - on PC it is working fine, but on mobile it is not

 

Please if someone have stumbled upon such issue to help me, i tried to find solution for 3 days but nothing..

Just to update that i continue with my research but unfortunately nothing works.

Since i installed prestashop 5 years ago it made me a full time coder, now i am searching for freelancing jobs .. without the jokes i really can not recommend PS to any of my friends or clients..
