To the serious folk - relax a little. This is Mildly Infuriating, not I'm dying if this doesn't stop. As a non-native speaker I was taught a certain way to use the language. The rules were not written down by me, nor the teachers - it was done by the native folk. Peace!

Do you know the correct times to use practice vs practise?
Noun vs verb? That’s the case with licence vs license, at least.
They’re both license in American English.
Edit: Same for practice.
