Are you sure your Wi-Fi is actually good? Like, not “it shows full bars so it must be fine” good, but actually stable and optimized? Because there are plenty of setups that look great on the surface but fall apart the moment you try doing anything more demanding than scrolling social media.
Furthermore, have you done any basic troubleshooting? Clearing the cache, reinstalling the game, and checking for background apps throttling your connection or even making sure that your device has enough storage? You’d be amazed how often weird issues magically vanish after those steps.
