Tapping button in Widget does not update App until force quit

I think this is a bug, but figured I'd double check in case I missed something stupid.

I have the following model:

class Thread {
    var id: UUID
    var timestamp: Date
    var style: String
    var fit: String
    var brand: String
    var size: String
    @Attribute(.externalStorage) var image: Data?
    @Relationship(deleteRule: .cascade) var worn: [TimesWorn]
    var wornCount: Int
    @Relationship(deleteRule: .cascade) var washed: [TimesWashed]
    var washedCount: Int
    @Relationship(deleteRule: .cascade) var fitPics: [FitPic]

which I am accessing via the following method in my app intent file:

 func perform() async throws -> some IntentResult {
        guard let modelContainer = try? ModelContainer(for:Thread.self) else {
            return .result()
        }
        let descriptor = FetchDescriptor<Thread>(predicate: #Predicate {thread in
            thread.style == threadStyle
        })
        let threads = try? await modelContainer.mainContext.fetch(descriptor)
        
        if let thread = threads?.first {
            let newWorn = TimesWorn()
            thread.worn.append(newWorn)
            thread.wornCount = thread.worn.count
        }
        return .result()
    }

TimesWorn is super simple, just a timestamp.

Basically running into two issues:

when I hit the button in the widget tied to the intent, wornCount will not update in the widget UI so there is no feedback that anything has happened. if I instead use worn.count in my widget text view, it does update immediately.

To add to the weirdness any places in the main application where I am using wornCount do not update until I force quit the app and relaunch.

Please forgive me if I am doing something dumb here, or am asking this question stupidly. this is my first swift app and my first ever forum post!
