Removed my iPhone under people in find my app as kept showing location not found

I finally figured out how to fix it and re-add my iPhone 11. Under people under find my app, selected the + and share my location. However, must enter the iPhone 11‘s phone number, not email address or Apple ID. Then it took me to a dialog box that said unable to share as share this iPhone 11 was disabled, giving the option of OK or settings. This time I selected settings, and took me to a long list of options which you could turn off or on, like the long list under analytics, which made no sense. I’ve been there a few times before but didn’t notice that one item was not on, share this iPhone 11. I turned it on and viola everything started working on both my wife’s devices and my devices.

later trying to find the locations of where this was disabled, I cannot find it, so wondering why or how it became disabled. It’s a location that’s never described anywhere. If anyone knows where this long list of settings is located please let me know. I found the solution to the problem by asking the right question, and took me to Apple community with a link to add or remove devices under Find My app. I’ll upload a screenshot of this page, link I was sent to. Best, Seth

Finally found where the setting was located. Under system services, under privacy/location/at the bottom you’ll find system services. This will open the page that was referring to with a long list of options that you can turn off and on. 2/3 of the way down was the option to share this iPhone 11. Why it was disabled I have no idea, but turning that somewhat difficult option not mentioned anywhere that I could find, fixed everything. Best, Seth

Hope this helps some folks down the road
