I just got an email Back from Google about this problem:
Fixes were pushed on February 27th, they include:
- Telling the user on the Quota tab that they have to enable billing
- Removing the option to change the quota when billing isn't enabled
- We no longer show a red warning triangle that 0% of 0 quota has been used
What we haven't fixed is the link to the document on how to apply for a quota increase, the bug for this has been bouncing backwards and forwards but we seem to be closing in on a resolution.
