Well this puzzle was crazy for me. Slow and tough.

For a lot of it, I didn’t even think I’d finish. But there was one clue that I couldn’t figure out, but when Calah looked at it, she got it immediately.

1A Its logo has a blue, red, orange, yellow and green “M”: GMAIL.

I had thought that it was a logo that had many M’s. When Calah right away figured out what it is, I looked at the favicon of another tab in Chrome and saw the multicolored M they were talking about. If not for Calah, no chance I finish this puzzle.

The title of the puzzle is Six-Pack, and I still am not certain why that title is applicable to this one.

I figured out the formula of the theme about halfway through the grid’s completion. Not halfway through the time because I was stuck awhile.
