What's happened to the daily jigsaw?

Have been happily playing the daily puzzle every day as part of my wake up routine, for years,and particularly, the jigsaw. It's been a fab app (apart from having to log in to check your answers) for all that time. Last week, I opened the daily jigsaw, only to see yesterday's. That's been the case since then, still the same puzzle every day, yet the other puzzles are still changing daily. I've deleted it and reloaded, to no avail.

What's going on? There's no way to contact the devs that I can see, so, presumably they don't care? What a shame.

Very good but room for improvement

I really enjoy this game, but why do I never get tough/diabolical puzzles at the weekend (when I have time to do them)?! Would very much like to be able to set my own difficulty level.

Also some form of tutorial on how to solve the really tricky ones (so that I learn).



Anyone else having trouble with jigsaw. Like these puzzles but they frequently seem to have problems loading. Can only load jigsaw on an old machine. Also difficult to write a review, doesn't accept nickname, tells me it is already taken, it is: by me.
