Can't play with my friends!

I’m sure this is still happening to many people. I cannot join to my friend’s game. It worked like 3 times only while we were playing and it took mostly around 40 minutes of constant inviting, linking and unlinking shift with epic launcher. It is very annoying. Today we didn’t join even after whole hour of trying. I guess staff dont read these these at all, so I would just like to adress it so staff knows and I would like some tips that could help me :confused:
