Hi everyone, PDF content is blank after download in IOS

[LMkhitaryan]

Here my config..
var content = document.querySelector('#RCH-pdf');
var opt = {
margin: [-10, 0, 5, 0],
filename: 'Summary Report.pdf',
jsPDF: { unit: 'mm', format: 'a4', orientation: 'portrait' },
pagebreak: { before: ['.audit-block', '.new-items-list', '.block-ops:nth-child(3)', '.block-fs:nth-child(3)', '.block-fs:nth-child(8)', '.block-ops:nth-child(8)', '.block-fs:nth-child(13)', '.block-ops:nth-child(13)', '.block-fs:nth-child(18)', '.block-ops:nth-child(18)', '.block-fs:nth-child(23)', '.block-ops:nth-child(23)', '.block-fs:nth-child(28)', '.block-ops:nth-child(28)', '.block-fs:nth-child(32)', '.block-ops:nth-child(32)', '.block-fs:nth-child(37)', '.block-ops:nth-child(37)', '.block-fs:nth-child(42)', '.block-ops:nth-child(42)', '.block-fs:nth-child(47)', '.block-ops:nth-child(47)', '.block-fs:nth-child(52)', '.block-ops:nth-child(52)', '.block-fs:nth-child(57)', '.block-ops:nth-child(57)', '.block-fs:nth-child(62)', '.block-ops:nth-child(62)', '.block-fs:nth-child(67)', '.block-ops:nth-child(67)'] }
}

html2pdf().from(content).set(opt).save();
