Photography / Image Rights: YouTube Content ID false claim

Quick background on my situation — any input appreciated lol.

YouTube Content ID false claim. I've been dealing with this for about 14 months now and the situation isn't improving.

This involves software/code I developed over the past 21 months. I do have documentation proving my ownership and timeline.

What are my legal options here? Is it worth pursuing?

NAL, but from what I've read, you should file a complaint. That said every case is different so take this with a grain of salt.
