Problem uploading images on mobile version of my site

Hi,

I have multiple upload buttons on a page for a custom form on my site. They work perfectly fine on the desktop version. On the mobile version, the first upload image button works fine. When I click the second upload button, the options “Take Photo or Video”, “Photo Library” and “Browse” appear as normal. Sometimes (not always) when I select photo library, it goes to open my photo library but then tells me that I have no photos in my photo library (which is obviously not accurate) - and so I’m therefore not able to upload a photo using this button. I have to refresh the page (sometimes multiple times) before the button begins working properly. Any ideas on how I can fix this??
