Informant 4.94 uses an old framework that is no longer supported by Apple. What this means is that the application cannot be updated it cannot be changed.
Our weather feed provider advised in late 2017 that they were raising the cost of the weather feed substantially. Since Informant 4.94 is being phased out it is not generating enough revenue to support the cost increase so we attempted to negotiate with them when that was unsuccessful the weather feed was turned off. Since the application cannot be updated to use a new weather service there is no restoration possible.
Informant 5 does have a weather feed and will continue to. Since it is a subscription based application the costs of the weather feed are more easily covered.
