Moving all objects from one layer to another in Lucidchart
I've read the related post Moving Multiple Objects to a Layer but it doesn't provide the steps for me to successfully accomplish. My diagram with the 4 layers is un-workable as I cannot figure out how to align the objects that are in different layers SO I'd like to simply move them all to a single layer. However when I select a layer & it draws the box around all the objects in that layer and I select "Move Objects to Another Layer" and it shows the target (original Page Layer) BUT nothing happens. Can you please provide the steps and an example to move all objects from one layer to another. If there are any nuances for multiple layers please provide details - my diagram has 4 layers.
