Font size changing

This has happened a few times so far. I have the screens and font set up to my liking and then return to the board and magically the font sizes have changed to a smaller version. This happened this morning and I have not made any changes since logging in earlier today.

Is there something reverting to the smaller font occurring that I am not aware of?

Went back to my settings, re-saved them exactly as they were and the font size is back.

Always helpful to show screenshots. Are you sure you clicked ‘save’ when you changed the font size???

Yes, I saved it. When I looked the settings were all correct, the actual view was not. If it happens again will screen shot it
