Missing GPS in form submissions

I had sent data on September and October 2023 for 34 farms using ODK App but I have wondered why the receiver end says data for 28 farms misses GPS and so I have to get the coordinates written on my notebook and send via excel document. How can I even retreave it because it doesn't display on SENT forms?

What version of ODK Collect are you using? What server (e.g. ODK Central) are you using? If you aren't sure, please post the link to the server.
