Are you using Apple’s email app?
If you use Apple’s email app, remember that there is a limitation at 15MB attachments. Unfortunately, we cannot change the limit.
If you have created a moving report with many photos, your report might become too big which can cause problems with sending the report via Apple’s email app.
If you have other apps such as Gmail or Outlook installed on your device, you can try using one of these instead.
You can also share the report through, for example, Dropbox, Google Drive or other alternatives in case you have one of these apps on your device.
