I have a Oxygen Web Author servlet (Apache) sing an Oauth Consumer key/secret to access Bitbucket repos. Recently numerous users have been denied write access (they can still read, and even create files, just not edit them).
A few notes:
--We've been unreliably able to workaround this by removing a user's access to numerous repos.
--Newly created accounts have no issues
--This affects accounts with write and admin access
--No combination of access for the Oauth consumer works.
