I use zd1200 and APR310. I found problem with feature Guest pass self service on firmware 9.12.2, 9.12.3, 9.13.3. There is appear "Invalid CountryCode" when i submit the email. Kindly need your help guys. Thanks
I had the same issue. you need to select in configure-->guest access service then tick "Enable guestpass self service" you will get "Notification Method" if its nothing you get this error. I use email notification so I configured the email in configure-->email and that fixed it..
