Scenario

Observed behavior
The main fill color button cannot be used, but selecting a color from the fill color drop-down menu applies the color. The feature works normally in desktop Excel.

2
Open the Fill Color drop-down

On the Home tab, click the arrow next to the Fill Color paint bucket button instead of clicking the main button.

Pick a color from the drop-down palette. The selected cells update immediately.
