Anchor event listener not recording few transactions

[sunidhii19]

Hi,
I am listening to an event emitted from my program using @coral-xyz/anchor library but it is not recording all the transactions on mainnet. I am using quicknode pro RPC URL for establishing the websocket connection to listen to these events on my program. What could be the reason here?

See #1613 for more info on why this happens.

event-cpi feature fixes this issue but it's not as ergonomic to use e.g. not as easy to subscribe. See usage example here.
