Unfortunately Coinbase is retiring support for connections made using 'Coinbase Connect' or 'Coinbase Oauth'
Luckily this does not affect connections made for connections using your Coinbase API keys, and if you'd like to get this setup check out our Support Guide on the topic.
Of course if you get stuck, please do reach out to our Support Team (via your app or Support@Delta.app) who will be happy to help!
