Disconnect every time a substitution occurs (high-latency cross-region)

Platform: PC 

Game mode: League matches

Every time a substitution happens during an online match, I get disconnected. This is 100% reproducible on my end and is specific to substitutions — it does not happen at other points in the match. I am the only player in the lobby who gets dropped when a sub occurs; everyone else stays connected.

What happens

1. A substitution is triggered during the match (by either team).

2. The "warming up" screen for the substitution loads.

3. "Connection unstable" appears at the top of the screen.

4. I am disconnected from the match.

Expected behavior

The substitution completes and play resumes without dropping any player.

Network setup / suspected cause

- I play with friends whose connection is in South America; I am located in North America.

- My ping to the match is consistently around 178–200 ms.

- I suspect the high cross-region latency is causing the sub synchronization step to time out and drop me specifically, since I'm the only player affected.

Additional notes

- I tried disabling substitutions in the matchmaking settings, but subs still occur during matches — the setting does not appear to prevent them.

- I'm aware of general connection issues, but this problem is specific to substitutions. The rest of the match plays without dropping me.

- This has been happening for a long time and significantly impacts the experience.

Request

Can the team look into why the substitution sync step disconnects a high-latency client, and confirm whether the "disable substitutions" matchmaking setting is working as intended?
