Your clan shouldn't "stop" earning XP though some clans are reporting that. If you are losing in a normal multiplayer match you only earn 10XP per clan member in the lobby. Use the app and refresh about 30 seconds after a game and you should get an updated XP calculation. The in-game XP bar doesn't update very often.
I got on a chat with activation support and while we were on the chat we started to gain clan xp again. Sucks we missed out on about 4 days but it was only 4 days. If any others are having this issue try going that route. I did it while in game and it was not to bad. He didn't tell me why it was happening or that he did anything to fix it, but it magically started working once we were half way through out chat.
Figured instead of posting as a response to posters asking questions just to make a thread, hopefully make it easier for the community to find out about Clan XP & Rewards due to the lack of info out there. Nothing against yours, I think you did an amazing job with the screen caps of each reward! Anyways, I just wanted to make an easy to understand "condensed" list for those looking for information about Clan XP & Rewards! Something fellow clan leaders could simply copy/paste for use in their own websites & forums!
looks like my clan might be having the same issue, just failed to get updated for two clan vs. clan wins. Usually updates around 30 seconds after a match but its been over an hour and nothing. We're only 12,000 Clan XP from our Gold Tag, sure would suck to freeze at this point!
Hoping it will fix itself tomorrow, but in case it doesn't, may I ask where you contacted support? Thanks for any help!
