Height above ground unit not changing.

In Settings, I've set the Height above ground to Feet, but on the Map, it stays as Metres.

Is this happening on the website? Saving requires local storage to be enabled in your browser.

It's in the app on Samsung phone.
I've not used the website.
I've not seen a Save option after making a change in the mobile App's Setting.
I've not intentionally stopped the app from saving settings. Where do I check?

There is no save button here (the changes are saved immediately). Try closing and reopening the app completely (including from the background). Alternatively, send us a screenshot showing where the units did not change.
