Custom feature is GREAT! But buggy

I use this app for it’s custom puzzle feature. I have a Sudoku paper book that I never completed. I enter the puzzles into the app because the book is worn, ripped and dog eared. After solving my 1st custom puzzle I entered 2 more and solved them too. The bug is that the app doesn’t remember that I solved the 2nd and 3rd puzzles!!! It doesn’t even remember when I used the ‘save checkpoint’ feature 1 or 2 steps before completing the puzzle!
At this point I entered 6 puzzles and I deleted the 1st one. I completed the 2nd and 3rd but they still show as incomplete!
Does anyone know of another iPhone app that has the option to enter custom puzzles?

simple game app

I’ve tried a bunch of sudoku apps and found this one to be OK.

Pros: dark mode. No full screen or overly interruptive ads (in the free version). Nice set of options to control effects, input method, etc. I’m glad to see the “digit first” method is an option.

Cons: it doesn't remember the dark mode setting. When you reopen the app it defaults back to light mode.

No option to immediately flag wrong numbers.

...not a “con” per se but a suggested improvement: “dark mode” could have less contrast. = even less strain for the eyes.

Also, PLEASE consider putting a “dark mode” filter / tinted overlay on the ad area. Stark white or brightly colored flashing ads kind of defeat the purpose....
