Travelling from Istanbul airport to Bristol

Hello, I have a flight tomorrow through easyJet from Istanbul to Bristol.

I’m very new to flying but from what I’ve heard Istanbul is a massive airport. From what I believe, my gate number will only be sent to me 30 minutes before it closes.

I also got an update from easyJet saying I will have to go through an additional security step, so I must arrive at the gate at early as possible.

Is there no other way to find out my gate number earlier?
