Apple Maps Pins Changing Location

Morning,

I am having difficulties with Apple Maps pins, and I am trying to see if it's a limitation of Apple Maps, or if maybe something else is going on. I've seen a few similar posts, none resolved, but nothing that seems to be this exact issue.

My job has me working remotely, and all over the world. I've been using Google Maps' My Map feature to create a map of where I've worked and been. As I've moved farther from the Google ecosystem, I figured I'd try and replicate something like that using the My Guide section of Maps.

The problem though, is that any of my dropped pins, or marked locations are reverting away from the GPS location that I've set them at when I enter them, and instead showing up at a nearby road, or municipality once I reopen the app, or go into the Guide. So instead of having 10-15 pins spread out geographically by the coordinate, I've got 10-15 pins in a random community central to the municipality the pins were located in. My notes that were on each pin are overwritten by whichever the last pin added to that municipality was.

Is there a way to force the pins to stick to the GPS location//coordinates that it was marked//pinned at, or am I stuck continuing with Google Maps or finding an alternative?

Thanks!
