Hello! Please tell me, in some programs (Mail.ru, Whatsapp, OK, VK) if you do not use it for several minutes, then notifications about messages do not come. They appear only when you enter the network, including if you open the browser. I have never encountered other devices before. Alerts for these programs are included.
First of all, go to Security - Battery, click on the gear from the top right and turn on Smart Sleep. Then in Security - Permissions - Run in the background, Allow work in the background "Google Play Services" and "Google Services Framework" and allow work in the background to those applications that need notifications (just do not overdo it).
If it does not help, then go to Security - Data - Network Access, the Background tab. There, for the necessary applications, select "Data transfer in the background is allowed."
