Let's say that you shared your front door with Jane until Sept 1, so that she can make some repairs. A couple of weeks later, Jane lets you know it's taking more time than planned, so she will stay until Sept 15. You can easily edit her access to extend it until Sept 15.
Here is how you would do it.
1. Select Front Door from your home screen
2. Scroll down and go in the access management section
3. Find Anna in the list
4. Here you are. You can edit and save your modifications.
We will let Anna know you edited her access.
And if a couple of days later Anna tells you she has to leave now, just repeat the steps and tap on the trash icon to remove her access.
