Questions regarding Coinbase and ETH

I'm having difficulty reaching any human at coinbase pro to help out, so I'm grasping at straws here. I sent some ETH from binance to coinbase pro. When checking etherscan, the transaction is completed, and i can see the ETH show up as "pending" in my coinbase pro portfolio.

​

This transaction happened 6 days ago, and it's still "pending" in coinbase. So my question is, is the Etherium network just really congested? Or is coinbase holding my ETH hostage and they need to clear it internally somehow?
