I am on pc and trying to play with my friends on minecraft and keep getting the unable to connect to world glitch

I have just downloaded minecraft bedrock instead of java so that I could play with my friends and I am unable to join them. Every time that I try to join their game I get an unable to join world glitch. This is terrible the game is one of the largest in the world and it has the worst multiplayer versions in history and you all have done nothing to fix this.
