Due to a technical change on the part of the netatmo infrastructure, it is necessary to install and use the latest myatmo version available in the App Store.
Old versions of myatmo are no longer supported due to the changes to the netatmo authentication, an update of these old myatmo versions is not possible.
It is therefore essential to update to the latest version of myatmo. If you are using an old iOS version that is no longer supported by the latest myatmo version, you must update iOS or use myatmo on a device that has the latest iOS version installed. Due to technical limitations of old iOS systems, it is not possible to provide the latest myatmo version on outdated iOS versions.
Please make sure that all your devices on which you use myatmo are registered under the same Apple ID as the device on which your myatmo Premium subscription was purchased. If this is not the case, a myatmo Premium subscription will be moved (!) from one device to another if you want to use it on multiple devices. This means that the Premium subscription will be deactivated on one device and activated on the other.
All your devices must display the same Device ID at the bottom of the myatmo Premium purchase screen. If different Device IDs are displayed for each of your devices, then your devices use different iCloud accounts and it is not possible to use myamto Premium on all devices in such cases. Please refer to this FAQ.
