I posted this on Reddit, but doesn't seem like there is a lot of traffic:

CoinTracking (Coinbase API) says Key Invalid.

I've recently purchased Cointracking and I followed the instructions and gave only read access that it needed to the newly created API Key. On the site it says "Key Invalid" next to the API key I've created and entered. I've also deleted it and added it back, as well as creating another API key and adding that with all read access. They all come back as Key Invalid. Is there an issue or something I'm missing? I've added API keys many times before to other configuration files and sites.

Any help would be appreciated.
