The Ready State Virtual Mobility Coach is like having a virtual Kelly Starrett in your pocket.
You want to work up and downstream of where you see the issue.
Where you see the issue isn’t always where it originates.
Do some work in the pec minor area and see if it helps.
Have you worked on opening the front of the shoulder? Opening under the pec? collar bone area?
You need to address everything in the area that is painful/tight.
