Shouldn't be an issue. You just need to approach it without looking ahead so much.
So you start just treating it like any other bluetooth keyboard - don't even think about tweaking, customization, etc. This means the only thing you're getting used to is the reduced vertical spacing of characters and the character differences - basically numbers and symbols - that you have to press the space bar at the same time.
As I recall, it took me about 4 days to get up to 40+ wpm at 97% accuracy (on a regular keyboard was usually at 50+ and occasionally over 60). After typing awhile like that, I got an idea of which keys I tended to miss. Mostly I practiced words with those keys more, but eventually adjusted the boundaries in settings (this doesn't make a big change, but it can help). And after a lot more time I considered further customization but as far as the main typing layers, I've done very little of that. On special layers, like number pad, there are a LOT of unused keys so I put a bunch of stuff in those to suit me.
In short, pretend it is a plain keyboard, adjust to that, and then in small steps you can have fun taking advantage of the other things it can do.
