Our App hosting company experienced a system wide technical failure. They worked tirelessly yesterday and into the night to get our app moved to a new server location and to send this new location to the App Stores. You will need to update your app inside your app store the next time you want to use the DMR NC app. Check the latest version date before updating. If the date is June 1st, then please update. If the date is not June 1st, then your app store has not refreshed their system yet and it will take some more time. If this is the case, use https://dmrnc.web4uapps.com/ for the immediate future until your app is ready to be updated. I am so sorry for the inconvenience and appreciate your patience.
Have a blessed day
