How did this get through the cracks?

Has no one in the QA team thought of someone joining someone else's session mid-mission? Because I'm getting hit by an infinite loading screen trying to join my friend's session while he is doing the 1st mission.

Common issue only mention infinite loading screen when starting operations not the current issue I'm having.

Rendering Bug, That infinite loading screen issue and so on, Game is just flat out unoptimized
