I'm running 6.8.3 and created private keys and logged in twice. Everything went smoothly. However, only My Subscriptions works for me. All other categories give me Quota Exceeded Error. I made sure that "Allow Developer Keys" is enabled too.

What can be wrong here?

I have the same situation, also no preview images in My Subscriptions. Any fix on the way or at least some response to this problem?

I was finally able to make this work by creating another project in Gloogle Cloud. I believe the problem was that my original project was old and, even though, i deleted and created API key and Client ID, something in Google settings has changed. After creating the second project from scratch, the addon started working, including thumbnail images, which also did not work for me before in My Subscriptions.
