App: Project settings
The app's Project Settings menu can be accessed from the app menu.
Normally, changes to projects are synced automatically. For example - if someone else adds a trap or bait station to a project, this will become visible in the app within a few minutes.
Clicking this button will immediately flush the project cache and force a refresh of the entire project.
Refresh map tiles
This will re-download the map tiles for the project. This is usually not necessary, but if your map has gaps, this button may help download them.
Max tile set size
This is the number of megabytes dedicated to the map tile set of this project.
If you need better resolution on the map you can increase this value at the cost of space on your device. Equally, f you are concerned about the lack of space on your device and don't need the map detail, you can decrease this value.
If in doubt leave it at the default (100).
The Hi-Res zoom limit indicates which zoom level the tiles will start to degrade at. The maximum zoom is 21, so if yours says 13 / 21, the map will get increasingly fuzzy as you zoom beyond zoom level 13.
