Notifications don't work properly.
Hi!
For the last couple of days I started noticing that notifications in several messengers don't work on mine and my husband's iPhones. For example I use Viber or Telegram. Only when I open the application, all new messages appear and I see them. But it happens without any notifications before that. I often use "Did not disturb" mode, but this issue occurs regardless of it. Of course I checked system settings and all notifications are on.
If you could help resolve this problem, I would appreciate.
My iOS version is 12.2
Thank you,
Volha
