Jigsaw - can't change settings (Explorer crashes, reloads)

Jigsaw has been deteriorating gradually on a day to day basis. Shortly after Windows update at the end of August, the Jigsaw App has gone 'berserk'. The total accumulated points disappeared, the daily challenges began to dysfunction and eventually resulted
in having to perform each 2 or more times by reloading and playing... then the next step required multiple play and the third became a repeat of steps 1 and 2. Today... 08 September 2020, the app does not load... I have tried every part of the Jigsaw app and
if the issue requires access to the Cloud... it will simply 'Fail'. Any part of the App which features 'Advertising' is impacted greatly by the interruptions due to a damaged video clip[ or a faulty advertisement.. often followed by a crash and the extent
of work is lost... Puzzles featuring 500+ pieces or more fail to actually trigger their completion and then crash... the recent opening preview returns to 0 percent and you can't get the image to disappear... yet in the puzzle series it shows the completed
puzzle. The issue continues...

Ads once again freezing and crashing Jigsaw AND Sudoku

I tried your link to more complex technical issues. My problem wasn't in the list. Your second link tried to sell me all the puzzles I've already purchased. I started in the Xbox Insider Program Forums a couple of days ago. All I got out of that was
a suggestion to use the Facebook site. So, here I am. If you go back to the forums starting on 28 March 2017, you'll find that I wasn't the only person who had this problem. It was widespread. For about a month, I followed suggestions that the other posters
received. Some had success; most had failures. I got fed up and found my work around. Work a puzzle. Let it crash. Reload and work another puzzle. I uninstalled Jigsaw Premium then re-installed. All of my accumulated puzzle sets were gone. I could
go reload any of them without further payment. I can rework any of those puzzles without crashing. However, they do show that they've been worked. I have bought a few new sets. They are the ones that crash upon successful completion of a puzzle. After
I reload, the box is marked with a star on whatever puzzle I worked.

I have the same issue using Win 10 TP build 10041. Before with previous build, there was no issues. Looks like if software not able to download straight in one shot. is not able to reload from previous interruption. Second problem, if I turn my pc to tablet
mode full screen, Jigsaw and all other Microsoft similar games crashes, only able to play on window mode

I had that problem too, on internet explorer. Switched to my Google Chrome and no problems. Try that, or empty your cache and delete cookies etc., reload explorer and try again.
