I heard an interview with one of the writers where they said they conceptualized the show in blocks of 3 episodes with a 2 episode finale and episode 7 being a sort of transition. 1-3 are about the fallout of cassian murdering those guards, 4-6 are about the heist, 7 is the fallout from the heist. 8-10 are the prison break and the last two wrap up all the storylines. So your experience isnt unusual.
