I found that rather than ‘learning music’, it’s more fun and engaging to learn songs. When it’s fun, you’re more likely to stick with it than learning scales or whatever. You can do that later if you want.

Grab that Uke. Get the Uchord app. Go to Ultimate-Guitar.com (you can switch between guitar and uke tabs), pick a song you know and like, play the track in the background and practice playing the chords. Pause when you encounter a tricky chord change, stop the track and practice going back and forth between those two chords until it’s fluent. Continue and repeat until you can play the whole song without the background music. Note UG will show you chord patterns, but Uchord will show you all the inversions as well. Sometimes a different inversion makes for an easier chord change.

Each time you learn a new song, the next one gets easier and faster to learn.

That’s how I did it, anyway, when I picked up ukulele as an aging adult.

Hope that gives you a bit of inspiration to try.
