IKW:
I did the same, updated on the 6th of July. My results are very similar to yours. I did the RC update and the P4 update with the Go 4 App, with both completing. Re-caluated the IMUs & Compass, successfully.
First flight I too noticed the "brief" motors stopping upon stopping an accent or stopping a descent. Slight but, very noticeable.
The "wobble" for me seems to be in straight & level over 10mph. I have not had it do it under 10mph.
Your final 1 & 2, I have but, not #3,,, yet.....
Hope they come up with a repair soon!
