iPhone 13 Pro Max not receiving Telegram and WhatsApp notifications or calls
Need help with the iPhone 13 Pro Max. Notifications on some apps, such as Telegram and WhatsApp, have stopped coming. Even the calls don't go through. There is an up-to-date version of iOS . Communication calls, SMS, notifications from applications that are scheduled to arrive. But the messengers in the background don't send anything. Resetting all possible settings, reinstalling applications, nothing helps. The notification only comes when you log into the app itself. For example, Telegram downloads the connection when you log in, and only then the push arrives. Where to dig and to whom to run?
