Event challenges in Microsoft Solitaire doesn't show properly

I am experiencing exactly the same problem at the moment. It is happening with Solitaire, Mahjong and Word Games. Funnily enough it doesn't happen with Sudoku which doesn't play ads! The 'Microsoft Casual Games' ad (horrible ad) has never played properly
for months - it plays for a few seconds, freezes for some secs plays again for a few seconds, freezes and then totally drops out into the game - WTF!!?? It makes it extremely difficult playing the Events in Solitaire or even to finish one of the daily challenges
in Mahjong, Solitaire of MUWG. I've restarted the PC to no avail. I had formed the opinion that it is entirely due to the ads not playing nicely. How does one even refer this issue to tech support?

Me too. Tried rebooting machine, and uninstalling, then reinstalling MS Solitaire. I can play normal games, and daily challenges, but clicking on that Klondike Event just crashes MS solitaire.

Also get message saying no events scheduled. I played two Klondikes this morning from the National Solitaire Day Event but now cannot continue. Previous experience with trouble connecting to Solitaire service I've found the timer on my last challenge is
still running.

Unable to connect to Solitaire Collection Events. Receive a message saying i need to connect to the internet. Received just after completing daily challenge.

You can't pause it. Furthermore, the clock keeps running even when you're not playing. I completed 26 of 27 challenges in 1:15 this evening. Then I had to go out to dinner. I exited the Event and the quit Solitaire and slept my Windows 10 PC. I came
back and the Leaderboard still said 1:15. But then I played the final challenge in under 3 minutes, and Solitaire added in the time when I was away along with the time for the final challenge. Final Leaderboard time: 3:53 :-o

I and others have been complaining about this issue for months, and Microsoft hasn't done a !@#$%^&* thing. Having worked in the tech industry myself for years, the attitude they show toward their users was often summarized as "We're
Microsoft and you're not!"
