Im actually playing in No Limit arcade ranked mode on EU serveur, I have player more than 50 games my actual SR is 3026 (enough for being in top500) SMS protection was always active on my account and I don’t see myself in the leaderboard and my rank icon is still diamond.
Remember not every match you have played may have actually been in the EU region due to the limited player population in that mode. So you may still be short 50 games for a specific region. Try to keep playing games if you can.
