@Ryan Sharston - Depending on size of the objects on your board, only a 25% zoom out minimum should be normal. For example, I just created this board with a Small size sticky and can only zoom out  to 25%:

However, the max zoom in of 100% seems odd. I don’t get this in Miro desktop app in Chrome, Edge, or Firefox on Windows 11 64-bit.

Can you share your set up and any details about your board? Even a screenshot after doing a “Show all” - either right-click on board or use Alt/Option + 1.
