Explanation on the mistakes.
Every time I play they mark up a mistake and they don’t let you know what it was. It’s annoying, I want to know what I did wrong so I can avoid it.
Their reply did not help because I have no idea when the mistake occurred. There were no red markings that I could see.
It seems they mark it a mistake when the same number is used in the sum even though one of the same numbers is on a different line in a different square and it is correct!! Its very frustrating.

Hi, thank you for your feedback.
When you make a mistake, you can tap the incorrect cell and number. Then look at the same row, column, or 3x3 box. In most cases, the same number will be highlighted nearby, so you can see why that placement is wrong.
We understand that the current mistake hint may not be clear enough, and we’ll consider improving it so players can understand mistakes more easily in future updates.
Thanks again for helping us improve the game.
