And then you go to Settings / Privacy / Data and all you find is a link to the privacy policy and terms of service.

So you search online and find several relevant posts on a support forum, such as:

• I cannot find this setting
• The "on" option is grayed out
• I tried to set this to "on" but I got a cryptic error message saying to contact my system administrator

All of them have been open for at least a year, hundreds of users clicked the "I also have this issue" button, and none of them have any useful replies.
