I setup a github repo as instructed on the ZMK official website. I also played around with the mapping with ZMK studio and all the changes would reflect immediately. However when I'm done experimenting with ZMK studio and made a complete keymap, compiled through GitHub, and flashed, nothing is changing.
ZMK studio is still working.
This is really confusing. I have probably spent 6 hours researching this and have had no success so far. I've tried the keymap editor Nick made, I've tried modifying the keymap in files myself, and it's all not working.
