Widget refresh timeline

Hi all,

I've got a pretty simple app (basically a Hootsuite like and light).

I'd was hoping to create a widget that show the last post if it is today, or an view that encourages the user to create a new post.
To that purpose, I create a Codable model that I store in the shared UserDefaults (suiteName) and when I do so, I call the fefrshtimeline as follows :

Code Block 
func save() {
        let encoder = JSONEncoder()
        if let data = try? encoder.encode(self) {
            UserDefaults.group.set(data, forKey: "lastPost")
            WidgetCenter.shared.getCurrentConfigurations { (result) in
                guard case .success(let widgets) = result else { return }
                widgets.forEach { widget in
                    WidgetCenter.shared.reloadTimelines(ofKind: widget.kind)
                }
            }
        }
    }

The thing is, I put a print in the timeLine and it's never called. I also tried to change the snapShot method, nothing works so far.

Here are both methods from the Widget :

Code Block 
func getSnapshot(in context: Context, completion: @escaping (SimpleEntry) -> ()) {
        print("🏵 getSnapshot")
        if let model = ExtensionSharedModel.retrieve(), model.date.isToday {
            print("🏵 add model \(model.displayName)")
            completion(SimpleEntry(date: Date(), model: model))
        } else {
            print("🏵 no models to add...")
            completion(SimpleEntry(date: Date()))
        }
    }
    func getTimeline(in context: Context, completion: @escaping (Timeline<Entry>) -> ()) {
        print("🏵 getTimeline")
        var entries: [SimpleEntry] = []
        if let model = ExtensionSharedModel.retrieve(), model.date.isToday {
            print("🏵 add model \(model.displayName)")
            entries = [SimpleEntry(date: Date(), model: model)]
        } else {
            print("🏵 no models to add...")
            entries = [SimpleEntry(date: Date())]
        }
        let timeline = Timeline(entries: entries, policy: .atEnd)
        completion(timeline)
    }

The widget is static configuration widget.
I do enter in WidgetCenter.shared.reloadTimelines, but never in the protocol methods.

Thanks for your help :-)
