I have done a Repository clean up
git reflog expire --expire=now --all && git gc --prune=now --aggressive
git push
Its gone from 3.8GB to 4.03GB
After this but has not refreshed Repository details and is now stuck on 4.03GB unable to commit anything.
Locally it's down to around 400MB in size however it's not updating.
it's like git gc needs to be run on Bitbucket side?
