Discord delay to load text channels/General lag/Occasional disconnection of voice channels.

I bought discord nitro just to get 100+ servers on discord. 

However, the more servers I joined, the slower discord was to load messages, and it even disconnected me from calls from time to time. It also disconnects me sometimes when I try to read text channels. Now i'm in 200 servers.

I have a good system configuration: ryzen 7 3700, rtx 2060, 32GB RAM and 300Mbps of internet connection. The same happens in browsers (opera, brave, chrome), on my phone and in another computer I tested. I tried enabling and disabling Hardware Acceleration, tried using discord canary, and the problem remains...

I believe that this problem has been caused by the recent difficulties of the discord API to be able to handle this demand. 

When talking to support in Brazilian Portuguese, the solution I got was: "you should then log out of some servers.".

This is outrageous. Discord can't keep up with this demand, this feature of Discord Nitro of up to 200 servers shouldn't be marketable. I bought nitro just for this, and now it doesn't properly works, the only option i have is "leave the servers?"
