Hello, I'm a new developer in freelancer. I have many years of experience with HTML/CSS and Javascript/jQuery, and issues with iOS and Safari are very common. I have a Macbook with the latest macOS version, and I can emulate all kinds of iOS devices. iPhones and iPads. I watched the attached video and I have a few ideas I would like to try. I tried it on an emulator with iOS 13.5, and when I clicked apply it kept loading, it was frozen.
I use Filezilla as an FTP client. I also have experience with PHP and NodeJS, and other backend languages. I would love to hear back from you!
Best regards,
Alex
