We have a workflow where we generate GPX files for Garmin marine devices and then collect data within Field Maps. To help manage the hundreds that get created I was hoping to attach the GPX files to our survey boundary areas so users could easily download them and bluetooth them over to their Garmins. Unfortunately GPX isn't a supported attachment file type so I tried zipping them up to attach. However now in Field Maps I'm learning if you click on a zip file attachment you can't actually open it or download it even with a solid data connection. Is anyone aware if I'm missing something or if this is an actual limitation?
