Interrogative

[This puzzle was collaboratively set on stream with Special guest tallcat! Video here. We also set a much harder puzzle which I will also post.]
Normal sudoku rules apply.
Arrows: Digits on an arrow sum to the digit in the circle.
Between Lines: Digits on a thicker gray line between two circles must be strictly between the digits in the circles on the ends.
Have fun, leave a comment if you enjoy the puzzle!
PS: I stream solving sudoku like puzzles two days a week, as well as posting Let's Plays of puzzle games like Blue Prince. You can check out the channel, as well as some videos I have made about setting puzzles, at my YouTube channel here.
Solution code: Row 1

A lovely, gentle start to a year of solving. I look forward to struggling rather more with the harder puzzle. Happy New Year to you both.
