I am unable to export my apple health data. I have extended my screen timeout and Refresh the screen. I get a message that it is preparing my data and then that disappears after approximately 90 seconds. No further prompts are provided

Hi Chrisc72,

Thanks for coming to Apple Support Communities for help today exporting Health data.

Are you following these steps:

"Export and share your health data

1. Tap your profile picture or initials at the top right.
2. If you don’t see your profile picture or initials, tap Summary or Browse at the bottom of the screen, then scroll to the top of the screen.
3. Tap Export all health data, then choose a method for sharing your data.

Your data is exported in XML format, a common format for sharing data between apps."

After this, you should see the "share" page where you can send the data.

Is your iPhone fully updated to iOS 14.6?

Have you restarted?

Have a fantastic day!
