How do I avoid lags in multiplayer photon game?

Hi all, I'm new to multiplayer game development and I'm creating my first multiplayer game. I'm using Photon Realtime SDK with Construct 3. Everything works fine, but I have a lot of lags on players moving.

I'm using 8 Direction behavior in my game and just send event with player's x,y coordinates on "Is moving" event. I don't use any data structure as arrays, just text with x and y coordinates. I thought it's the easiest solution for networking games.

I didn't find any documentation or solution for Construct with Photon games.

I will be grateful for any help, any article, example or anything else.

Thank you!
