I can’t change the height of the rows…

Yes, try the 'Id" column.

We are using the Ninox 3.0 Cloud. It is working on both Windows and Mac here. On the Mac it is working with both Safari and Chrome. Are you using the default Id column on the left? What happens when you place the cursor under any Id number in that colum. It should change to a cursor with up and down arrows, allowing you to change the vertical height of rows.

I have maybe the explanation : I am on an Ipad…

This feature does indeed work on the iPad. Touch the leftmost column, the one with the line count. It may be a little tricky to find the exact place to put your finger to grasp the dividing line.

Thanks Alain.

Very tricky indeed…

For those who have an Ipad :

Place your finger on one of the bottom lines of a row in the row number column (not the ID): a very small gray rectangle appears > slide up or down
