Checking in from Iowa and I have the option here too when I hit the customize button. I do have to scroll down a bit?
You might try uninstalling and reinstalling. If on android, clear your settings before the uninstall. The mcdee app does tend to be kind of unpredictable.
If that doesn’t work, send an email to them. I actually did email on some problem I had and they responded pretty quick with a temp workaround and fixed it later.
