Hi @tuner,
I hope you are well today and thanks for posting here.
I have tested your site on my android Sont Xperia mobile and it’s working fine as shown in the attached screenshot.
Which mobile device are you using to test it?
Also please try using latest version of mobile browser and using different browser.
Best Regards,
Movin
