All of this. In version 1.8 there are no errors! My sketch works, but I cant update it.

Please post the code which compiles on 1.18 but does not compile on 2.2.1.

None of my sketches works on v2.2.1!

Looks to me like missing libraries.

Can you run Blink() or any of the ide example sketches with 2.2.1

9

trying testing

I'm using the old version. It's to annoying to have to struggle for days to try to make new things work while the old works 100%
