iOS 9 device owners (e.g. iPad 2) Please Read
On October 1st 2021, your iOS 9 device can no longer connect securely to a lot of internet sites including OzRunways, because of a missing file. This is normally updated regularly by Apple on the latest iOS devices, but you will need to install it manually because these old devices are no longer supported by Apple.
Please download the https://letsencrypt.org/certs/isrgrootx1.der on your old device. Open attachment and install when prompted.
You will get a few warnings: keep pressing 'Continue' / 'Install'. After installing this file, your OzRunways will work again
