lag/desync(help)

Options

hello. i uploaded a game on steam, but for some people they get very bad lag and desync. it works fine for myself and my friends who live near me. i tested it with someone from japan while im in u.s. and experienced the lag/desync (objects teleporting, glitching through walls). one person said the server desync could be fixed by using the multiplayer pause feature that i had and waiting for the other player to catch up (uses timescale = 0 and PhotonNetwork.MinimalTimeScaleToDispatchInFixedUpdate = 0)


the game has at most 40 objects with a photon transform view(not classic, all photon views use "Unreliable OnChange"), could this be too much and cause the game to break?(whats the limit?) what else could cause this issue? i have no idea.

i really want to fix this for my game as i already paid for photon servers. thanks.
