Alright guys, I've figured it out!
HuntStand is primarily designed to be mapped and updated by desktop or laptop. I don't understand why but it is. A desktop is the only place that holds true data and lets all features be applied. The only thing you can't do from desktop is GPS your current location and Sync. Syncing is for the on the go app via mobile device.
With that being said, the mobile device draws the data from desktop edits via Sync. No matter which desktop you've used to update, they will all be updated online. Once accessed from the mobile app, you draw that data from online.
I've seen multiple people saying that logging out of all platforms and devices sometimes fixes it, but most of the time this is not feasible. Some others have said clear your data and start fresh....ya no... don't do that. Think of the hours and time you've put boots on the ground to map and pin point all that info.
Do this one simple thing. Refresh the app by deleting it completely from your mobile devices and re-downloading it! Once you re-download it, it reads it as first time access and re-ups all of your data. From there you should be able to Sync without issues as I did just that! It kind of clears the app cache on your phone in a way.
I've had HuntStand for 5 years now looking back and this is the first time I have had an issue like this. Hope this helps everyone! Happy hunting!
