Every now and then Excel does not do anything when dragging a cell with a formula from the side, to apply it to consecutive cells. It just marks the cells without doing anything. Also marking cells and using Command + D does nothing when this bug applies.
This does not happen all the time, but it is quiet irritating. So far a restart of the computer used to work, but this time not even that helped much, since after restart it only worked once and stopped after that.
Using Office 2016, Excel version 15.30 (170107) on a MacBook Pro 2015.
