I created a crew in GTA 5 some time ago, but I chose one of the suggested emblems because I didn't have one myself. A few days ago I wanted to change the emblem, but it doesn't change in-game. I play on PlayStation 4 and have already linked and reconnected my account, but nothing happens! It changes on the social club page and it says that I changed it. INGAME but not!
Knows exactly what you mean, changed 4 days ago because I wanted the UMCO banner but it only changed on the page. I've tried everything and I really mean EVERYTHING to change it. Nothing helped, apparently the servers are so busy. It still annoys me to this day that it still hasn't been changed, unfortunately there's nothing you can do about it. Apparently this is due to the rockstar stone age servers.
But you could ask the support and say what they recommend. I have given up hope. Some say it can take 1 to 2 weeks.
