On some iphones, regardless if the user is using chrome or safari the sidebar is not rengering correctly. Please see attached screenshot. The users have cleared their cache but the problem still persists. The problem does not occur on android.
The issue is that your SVG images don’t have width and height attributes.
You need to open your SVG icons file with some editor like Sublime Text or default system text editor and add width=”31″ height=”40″ attributes to your svg tag like it is shown. Then you will need to re-upload your image in WordPress Dashboard.
