Telegram began to update / synchronize for a very long time. What could be the problem?

Question

macOS

Telegram application from the store.
Messages arrive with a delay of two or even three minutes. Even if you open the application, it will not synchronize for 30 seconds, but it does not show the "connection" status either. Because of this, you have to keep the tab open in the browser of the web version of the telegram ... What could be the problem? Maybe you need to allow work in the background somewhere?

Answer 1

I found the Telegram Lite application in the store, it looks like this is the Qt version of the application, which is made for Windows and Linux. I had no problems with him. Let's try and see.
There is also a version of the telegram version dmg, from the official site. I'll try too. If I do not forget, I will write as a flight.
