We just checked on our end and are seeing it load. Could you try a hard reset on your console and see if that helps?
Can confirm same issue on PS4 NA. Endless "loading data" screen on guild history, guild bank history, and sales history. ALL past data is gone.
I updated MOTD (to tell people to mail me donations instead of depositing for a contest I have going right now, since I now cannot see who has deposited gold since the last time I checked last night). The fact that I updated MOTD does show in guild history, and one item in our trader sold while I was online so that showed as well.
I then had to log off to go back to work. I will be curious to see if that data that logged while I was on remains or gets wiped clean. Or if any history between now and when I log on tonight will show.
This is a crisis situation for guilds who rely on knowing who deposited into the guild bank for dues, raffles, etc. Not to mention open guild banks can be robbed with impunity if you cannot see who withdrew everything. And if we can't reliably see sales history, we have NO idea how the guild performed at a trader and if that trader is worth bidding on again or trying elsewhere.
Basically, literally all essential guild tools are now gone. They were already limited, but now we have nothing but a gaping void.
And yet ....Yes, it would be hilarious if ZOS blamed guild history not loading on Xbox/PS4 on addons!
No addons here ...
