Snip the leaf off and have a beer and walk away..... That's what I do.

Now that's advice I can follow! I was already half way there.

I left mine, but it doesn't matter what you do with it. The plant will get rid of it wen it wants to

Boy, I wish I had that problem, my peppers are dropping multiple leaves daily due to all of the precipitation we've been having in the northeast. I hope they even survive this onslaught of rain. If so, hopefully without any fungal ramifications.

Be well,

Leave the leaf be. Half of it is a healthy green and is producing what the plant needs.

If you are not happy to see the burned leaf then cut off the sunburned part and save the half, it is healthy, just like Jean mentioned. I had many like that, I cut them all half. I do not recommend to cut off the whole leave. Just I share my opinion.
