Always keep my angle low, but now it seems like after joining challenges or OTLs the camera angle option will swap to high on it's own and I have to open settings and change it back.
Ideas
Same, using fast travels triggers it for me. I have RS to change camera height enabled in advanced camera settings so I can switch back, not everyone uses that tho.
I noticed this as well, sometimes the game is registering you pressing RS to switch camera angle even though you're pressing RS to fast travel.
