Coinbase is technologically kind of a joke. Their matching engine is crap. They haven't even adopted bech32. They just do the bare minimum to keep things working for 99% of users, and for the unlucky 1% they follow the same customer support strategy as Google (aka automated emails but no actual humans). Unfortunately Coinbase is YC and they do a lot of marketing, so people who are just getting started tend to think they're a frontrunner.
If you want an exchange that keeps up with the ecosystem you should use someone else. Kraken qualifies: https://blog.kraken.com/post/13502/kraken-now-supports-insta...
