Inconsistent grouping of notifications

I'm sending push notifications to a notification extension, and within the extension setting the threadIdentifier to be the same.

But I'm observing inconsistent grouping behaviour, and behaviour that changes over time.

The general iPhone settings are to display notifications as a Stack, and the app settings are to show on lock screen, notification center and banners and the notification grouping is set to by app (changing it to automatic doesn't affect the behaviour below).

Pushes are displayed on the lock screen grouped together, then if the device is roused and the screen swiped down to reveal the notification center then they are still grouped. So far so good.

If the iphone is active then the notifications appear at the top of the screen, one by one, but in this case if there is a swipe down to reveal the notification center then the notifications are not grouped when displayed, but shown individually. But then if one waits a few minutes and then displays the notification center for a 2nd time, sometimes now they will be grouped, but sometimes not.

Why are they not (always) being displayed as grouped in the notification center?

As the Notification Center is the process that handles this, and works separately and asynchronously from the app which owns the notifications, some delay in expected - especially if the AI features are also turned on to process the notifications to summarize, etc.

But if the delay is indeed "few minutes" perhaps a bug report is in order.

To file a bug report, you can use the Feedback Assistant.

Don't forget to include as much information as you can about the cases you see this problem with. In this case screen recordings would help.

If you have any questions about filing a bug report, take a look at Bug Reporting: How and Why?
