In Wikipedia Mobile App I receive push notifications from Echo. The problem is that those notifications are old notifications, but they do trigger when there is a new notification.

For example when the notification on the second screenshot happened I have received the notification on the first screenshot:

Those are older notifications, some of them are from ten days ago:

As a note I will add that my Echo usage pattern in the browser is that I open notifications, sometimes click on some of them, but I never click on mark all as read, so the number gets incremented with time and it is by the blue or red background or lack thereof that I determine if there are new notifications.

I expect to only receive notification about the new event that, the one that in the browser triggers red or blue background.

I currently have Version 2.7.50399-r-2022-04-04 of the app running on Android 12 (One UI 4.1) SM-G998B/DS device.
