There's a glitch where Zoom may not give you any oxygen if you've just been hit.

I was on a WR-pace run last night when it happened to me and ruined it. Specifically on Limestone Ridge 3, I was redlining it because of a slip and Zoom didn't give me any oxygen, despite still losing her tank. Caused me to die a room or two later and ruin the entire run. I was not happy.

In a slight silver lining, it's the first time I've seen a glitch in this game, which means there may be more - exploitable - glitches out there.

So just be aware of that in your future runs.

I know Zoom holds position when you leave the screen, but that's unfortunate. I guess you're completely immune to everything when you're blinking, good and bad. Does that apply to the final gate too? Capsule pieces / red green radio cubes?

I'm sure there are more exploitable glitches; I completely stumbled on the sideways-question-skip by accident. Sure would be nice if there was a way to wall clip that way...

I know you can still pick up capsules, hit the combo lock, and trigger questions when immune, so not sure if there's more there honestly.

I think the combo lock question is tied to the frame that you trigger the wall, so I don't think you can wall clip it. However, it may be possible to time it precisely to get a good combo, or if it's RNG, to use some sort of RNG manipulation to get the right combo. I need to go back through my recordings to see if there's any pattern.
