I cant complete any quest.

I can second that completing the daily quest (attack with x creatures, cast y blue or white spells, etc.) causes all to disappear including the daily (250 Gold, 25 XP) and weekly (250 XP) to disappear and not return until the next day when you get a new daily quest.

I managed to keep my daily quests/wins UI open today. I did it by NOT completing the daily quest until I had completed the 15 daily wins. First game after completing the daily quest the UI then disappeared.

I had this issue too, seriously stupid. I can't see any of my progress, quests, or wins, and I haven't gotten any of the rewards for them. I've closed and reopened the game like 4 times, no results.

@mufur#66902 As far as I can tell after checking after every game:
my points on the mastery page
my collection for any new uncommon
or my vault for an increase of .3%
You receive rewards until you achieve the next level of mastery after everything has disappeared, then nothing. Of course I can't be sure, and neither can you.
This all avoids the main point that this is a UI issue that should've been caught in QA/Testing. With a work history in tech and a four digit DCI#, I can tell you this points to poorly designed system architecture (because these kinds of bugs happen after almost every major update), and poorly run/understaffed QA/Testing. I never saw these issues in all the years I played Hearthstone. They seem to have a well run organization.

Well they won't be getting anything from me if this continues they used to not have this problem and its pointless starting the game up again with this annoying bug.

plz fix this ...pleaseeeeeee

the whole bar of quests vanished

Happen again yester and today. After second win, they went missing.

just finished my cast 20 spells of blue or green and my quest bar dissapeared

Any luck on this bug. Just played 4 games and lost my progress bar.

Same issue, just started playing today.

Ive already posted about this bug for the past three days in a row, and no surprise that on day 4 nothing has changed, so no need to repeat myself about this bug, wizards you know what you need to fix, hopefully this will get resolved before the next set comes out.

Completed the color challenge, thought i would get a new deck, but when I returned to the home screen, all the quests and rewards are missing, the new color deck was missing and I cant get any gold or xp

same here this morning - still not showing. Also had a bug yesterday where I couldn't attack after choosing a creature.. had to skip and lose the game. would have won if it let me. was so angry.

hello there!
New day old bug.

this problem seems to have reared its head again.....been having this problem since release of new deck/cards

Guys, we all have the same issue. Not all of us know that we receive XP, gold, cards etc. it just doesn't show up as we used to. It's a little bit annoying - I know, but we receive what we should for winning. There is some mess with reward popping up and the "new" card mark, but we receive them. (and yes, I repeat that three times for a reason). Let's Stay calm and see you on the battlefield.

Same issue with not seeing the quests and wins wheel last night. I was at 10 out of 15 wins for the week and it went blank. I finished the Sealed Strixhaven event with 4 wins and accomplished a few additional wins afterwards to have completed the weekly wheel and daily wheel. Also, I didn't receive the rewards for level 6 in season pass which should've been a mythic rare (I did get the books, but it never showed up on my screen after wins) and cards that I should've received for the daily wheel didn't register. Will we all get the rewards after the bug is fixed? Will we receive a notification/email or maybe the rewards owed will pop up during our next login? Please Advise.
Attachments: I have one snapshot of the screen, and I hope the log helps as well.

This happens to me as well. I finish the first daily quest but my others disappear. What a ripoff
