Attendance on mobile browsers

Hello,
I see that someone else had this issue and was marked as resolved but we have no solution. [sorry I replied to a resolved issue]

We are facing the same issue. We tried with 5 different browsers on Android [chrome, Edge, Firefox, Opera and also iPhone safari]. If we go to attendance to add/update, the page has a grayish overlay and is not responding. If we switch to “request desktop site” from the mobile browsers there is no issue. The issue persists with both Admin and teacher accounts. There is no issue whatsoever using a PC/Tablet, but we can replicate issue if we are using for ex. chrome on a desktop and toggle to mobile view. Just as a quick experiment, I changed permissions on WPSchoolPress to 777, but the issue persists.

Thank you.
