Notifications not working on iOS

The app was fine then there was an update and it screwed everything up. Now all my iOS devices won’t receive notifications!!!!!

Developer Response ,

Thank you for taking the time to review our app JoeyandAlex.

We're sorry to hear the notifications are no longer working. It sounds like this may have occurred after an iOS update rather than our app. We are currently working on a new update to improve this function when used with the latest version of iOS. It's always important to keep the app and DVR firmware up to date. If have any questions regarding these processes, we offer videos and articles through our Support Center and have an expert Customer Experience team to assist you further!

Was working great but not any more

I have had this system installed a year ago and everything was great the app worked awesome, but now for the last couple of months it does not work on the app. Very disappointed. I have not received any help from the support line.

Can’t get any kind of viewing to work for my MacBook Air. Can’t get playback anymore on my iPad or IPhone....have to go and plug my TV into the system to see any playback....cameras keep going off so have to reboot the systems or hit save on the apps ... way too many problems so not there when I need it most. I don’t recommend because the software for online viewing is not reliable at all.

Thank you for taking the time to leave us a review. We're sorry to hear you've been experiencing difficulty with the app. There is currently an industry wide issue occurring due to a transition to IPV6 with mobile providers. We are working around the clock to find a solution and will update the app and DVR when the solution is complete.
