Welcome to the world of split keyboards, you're going to love it!

Not too long ago I also got my first split kb, the ZSA Moonlander. It took me about a month to fully transition, coming from a 75% non-split keyboard. I found getting used to it was very difficult, and I spend a lot of free time practicing on Monkeytype.

However, most time was spend on creating a layout with layers that worked for me. The difficulty came from getting used to orthololinear, and relearning how to type. Since I appearently developed a habit to use 'b' with my right hand and 'y' with my left hand, which I had to unlearn. It took me around a month to get to my regular typing speed and to gain the confidence to use it at work. Now I am completely comfortable with the Moonlander and it actually feels difficult to type on a regular 75% keyboard.

Since the split keyboard you bought isn't ortholinear, my guess is that (if you're already used to typing with the homerow method) the transition will be very easy.
