That's a real bummer :-( . I use the Firebelley course on Udemy and I love it. I have little reference except all the free tutorial context, but I feel this tutorial is in depth, explains clearly and at a nice speed. Also like the guys voice but that will be pretty personal.
Only other paid course in Godot I took was a book for Godot 3.4, I liked it but updating the code to Godot 4 took too much time. I see Mr. Bradfield has updated his book to Godot 4 though!
Actually started looking around for Godot lessons the same time last year because I checked out the courses in the Humble Sale and they didn't inspire me, so I went out to see if there was any paid course that did :-).
