(I use 2021.4.8 - preview 0931)
When trying to manipulate multimensional spreads in an IOBox, for instance
if I create one row, set its dimension to “n”, then change the whole spread slicecount to “m”, the m slices will have dimension n (as expected).
=> left IOBox in my screenshot
but if I create one row, set its dimension to “n”, then add 1 or more rows via the Configure > plus sign box, all new rows have size 0. I guess we’d expect the new rows to have the same size as the one holding the “+” box.
=> right IOBox in my screenshot
Hope this helps!
