Within the Profile tab (bottom right-hand corner), you have the option to edit your visibility for all task types and locations that are assigned to your profile.
If you do not see a specific task type or location when trying to post, go to your profile tab and click the appropriate header; you should be able to scroll through the listed items, and if you see the circle unchecked, tap it, and it should now appear when you go to post.
If you do not see it, then it may not be assigned to your profile, depending on your access, you may be able to add a new task type or location, but if you do not see this option, you may need to contact your market or regional director or whoever oversees your account as a company or email in to support at support@gohyer.com.
Note: Notifications will be disabled for deselected locations, and they will not appear on your task location screen.
