After completing Boss Blitz bosses on the 23rd of March, I was unable to claim the weekly rewards on the 24th of March. There is a red dot indicating there are rewards to be collected, but attempting to click "claim" just gives a "There are no rewards you can receive" popup.

Having the same issue myself. Hopefully they'll be able to address this soon.

I have the same issue on NA server Kamasylvia4

Steps:

Go to the Black Shrine icon

Click on Boss Blitz Reward 

Click on Receive Reward

Message : "There are no more rewards you can receive"

I have relog mutltiple time and even relauch the game and Steam

I have been trying since the usual reset at 00:10 UTC ( 8:10 pm my time ) every hour or so.

Please look into this issue

Thanks!

they sent a notice in game, everyone can't claim, it will be resolved soon

They have nbeen making in-game announcements about this for several hours.  Surprised they haven't posted an announement on the website.

came here to post i couldn't reclaim my rewards and saw your post, thanks for the screen cap!

r we going to get the reward after they fix or we getting nothing?

Does this mean we can do our new week and they will work it out or should we just wait it out? The message they ran doesn't make it clear exactly.
