The alarm still goes off in delay exit/home mode

Help! I got a new Ring home monitoring system. Two big questions: - I set it on Home/Exit Delay for the two main doors so my dogs won’t set off the alarm. But, the alarm goes off anyway as soon as I leave. Why, and how do I change that? - My personal workaround can be to press Home in the app once I leave, but what would my dogsitter do? Can I give her very limited access on an app? I’d planned on her just using her own code manually. Thanks in advance for your help .
