I searched if anyone had previously written about this issue, but I couldn't find any previous posts.

The problem is that, as can be seen in the screenshots below, I receive notifications much less frequently and rarely in the smartphone application version.

Even if I open the application twice or restart the mobile phone, this doesn't change easily. When I try to reload the page by sliding the screen down, it does not help either. Today, I had to reopen the app version for the fourth time to be able to see the same notifications as in the web version.
