Is the Dec. 18 Daily Challenge Classic Mahjong puzzle solvable?

I've been playing Microsoft Mahjong daily challenge for a couple a years now.

It's fun playing this game.

Sometimes is easy, sometimes it's difficult, but it was always solvable until yesterday.

Yesterday's lightning tiles challenge (August 16, 2021) is unsolvable.

It's obvious that I'm not the only one who came to this unfortunate conclusion.

Because there are of lot of other people who came to the same conclusion.

Daily challenges should be solvable. It doesn't matter if it's difficult, but they should be solvable. That's the definition of a puzzle, it's solvable.

Please Microsoft, do us players a favor and make this unsolvable lightning tile challenge solvable.

Edit August 18, 2021

Microsoft changed the positions of the lightning tiles, now this lightning tile challenge is solvable.

Thank you, Microsoft.

Amazed Microsoft responded so quickly!

Thanks to the team responsible!

17,465 challenges completed now.

See Arkadium's answer to "Previous Months' Daily Challenge Puzzles" for August 1st in the Mahjong forum.

Ditto. This happens in the daily challenge on the easy classic puzzle. This happens on my PC. this is the second day this has happened

All daily challenges are solvable.

Its only "solvable" if you are very fast tapping on the blue tiles while the previous pair of tiles is still on the fly. HTH
