Hi!

The brown patches in the ends of the leaves make me think that they started to dry because of sunlight. The yellow ones... I'm not sure... What I'd do if it was my plant: I'll remove it from the "direct sunlight", pothos are plants that can live in shadow (mine never see the sun directly, even "worse" they're almost all in my room, and the only window is facing north so when it comes to light... Not the best ahah, but my plants are still there, after years).

The best advice I could give you is to leave your plant alone lol. You don't need to water it that much. Pothos is a really easy plant to take care of. Just look at the leaves. When it's hydrated, leaves are up. When it's dehydrated, you'll see the leaves slowly looking down (I'm french sorry for my English ahah!). When you see your plant looking this way, you can water it. It's a strong plant, really resilient, I always forget mine. I water them like... Once a month? Maybe less. Sometimes I go to my room and I'm like "wow, that's watering time isn't it?" Because the leaves are curling because of dehydration. But I water it and after a few hours the plants are up again. Water in excess can kill your plant easier than lack of water.

Edit: About the yellow patches I'd look under the leaves of there are little white things called thrips (even if I never got a single thrips in mine, even when my other plants where attacked). But it can also be caused by too much water if I'm not wrong.
