If you embed your Awesome Table app in a Google Sites that contains images hosted in Google Drive, and you want to open the app on Apple desktop and mobile devices (Mac, iPad, iPhone) using Safari, the images in your app might not appear.
This issue is caused by Safari Intelligent Tracking Prevention (ITP) which blocks the images from being loaded. Google Drive attempts to create a session (loading an iFrame during the request), which is blocked by Safari.
Safari Intelligent Tracking Prevention is a feature built into Safari on Apple computers and mobile devices.
If your app is embedded on Google Sites, to make sure that the images appear correctly on both Windows and Apple desktop and mobile devices, you can transfer the images from your Google Drive to any other image hosting sites.
