When trying to claim items from web storage, and I open the "Select region" list, there are no regions to select, thus cannot claim items.

My Boyfriend and i have the same issue. Yesterday it was working

Have the same issue. 

same issue

Same issue

Just used a FLON-DORG-OLDE-NEGG, was not able to select any region and now the coupon is used, think it went to NA when I am EU.

Fix this pelase.

Same here. Additionally i can't set my "Main Character" under "https://www.naeu.playblackdesert.com/en-US/Adventure/Profile"

since it only shows me 1 Character I have on NA, although I mainly play on EU.

Same issue here. Seems to be an issue after the maintenance.

Same issue

Using the in-game coupon function is a way around this for now. I've just used it (in EU, not Steam) and it works.

Edit:
Also looks like EU has been yeeted off the forums. My Character is now showing as my lvl 56 NA toon I played once a few years ago! XD
