I was exactly in the same situation. And I would say ..if it wasn't for COVID, I wouldn't have landed on this.

learning using an app is low pressure, very pleasant, very game-y. Im at the point, where the game has gotten me interested enough that I wandered on the internet towards "Taubman method for eliminating RSI", etc.

I strongly recommend it for kids even. Im pretty sure this will get me flamed by people who play piano already, but I'm willing to bet money that for non-musical parents, they would be pleasantly surprised that their kids are doing something other than playing videogames...and kinda learning something awesome while stuck at home.
