How can I downgrade my system from manjaro 20.2.1 to Manjaro 20.2?
There is no system version. It’s all package versions.
Question is: Why do you want to downgrade? What is wrong with the current system?
What message do you get, when you go to twitch.tv?
“Firefox can’t establish a connection to …” That is not a problem from only twitch that is a problem from the most websites and apps. To Minecraft server, Discord, Chrome and other apps I have no Internet connection too.
