Problem: For some reason, the StructionSite mobile app will take up a lot of space. This may occur from taking a lot of photos or drawings being very large.
Solution: Go to the main page on the mobile app (that shows the list of projects). Tap on the menu on the top left, and select "Storage Settings:.
Then, tap "Clear Cache" or "Delete Stored Files" if the number seems large (i.e. several gigabytes).
