Tried on a brand new board as this was happening on another private one:
If I hold Shift and then Scroll with the mouse wheel, this _sometimes_ scrolls horizontally, but quite often the behaviour breaks.
It seems to happen if when I scroll without shift - after that, Shift + Scroll zooms until I reload or something else happens. Sticky ‘flags’ for zooming get wiped out on scroll action?
If you are unfamiliar with these settings, you may want to try each of them and see how Miro behaves. Personally, I always use a mouse, so I force mouse and when I use the mouse wheel, the board will zoom in/out, but when I want to pan the board, I right-click and drag.
But, back to your issue. If your settings are on Auto-detect, then perhaps Miro is sometimes getting “confused”, e.g., when it suddenly does not detect a mouse, it reacts with panning, but other times it zooms.
Can you tell us more about your set up, e.g.,

Hi,
Ok, I see what you mean there.
I am using an MacBook Air with an external keyboard & mouse plugged in, so generally using the mouse. On Chrome browser.
If I force the preferences, then yes, it seems to behave better. Maybe needs some kind of throttling / hysteresis on not detecting the mouse. I had got confused originally because I thought we were in Figma and the controls were not behaving. Compared with Figma - that is more solid 
Thank you.
