Are you a dev in general or a dev in the Nook Apps program? If it's the latter you can submit a support
If it's the former then I'm not sure how you can submit to the team. Perhaps contact Alex on this forum and ask to get it sent to team or go to Nook Issues Reporting thread and share it there.
Finally, are these Android 4.0 issues or MTP issues or Nook skin level coding issues?
