As of yesterday, when I make a line break in a Google Sheet cell,by using Ctrl Enter, the cursor moves down, however when I start typing, it types on the line above. In other words, the cursor no longer is on the new line. It's like the line break made a new empty row in the cell, but the typing continues on the previous line. I have: -re-installed a fresh Firefox, -started Firefox in safe mode, -tried it in Chrome (it works), -restarted, - tried on another, same model, computer (it works) -issue is in all my google sheets
