I've searched for an answer to this extensively and I can find nobody talking about it so I hope this means it's some easy fix I am missing....
Somethings drag & drop as expected and somethings don't. Some resources drag and drop correctly and some don't.
Example: I open my library and filter to 4 books I am currently reading: Can I Know God's Will?, Christ & Culture, Chosen by God, and Systematic Theology. 3 Of them I can drag over to favorites or a layout section or a shortcut or any valid drag & drop location. The Chosen By God resource will not drop anywhere. I can drag it but it won't drop.
There are other resources that behave similarly. If I have a multi pane layout and I want to move a tab to another pane, this resource and some others (Notes tab, any tab with a Reading Plan, several other library resources) will not drop.
If I am in my Favorites tab and want to get one of these misbehaving resources in there, I can select Add from the favorites menu and it will be added, but I can't drag & drop it anywhere to move it within my Favorites structure.
Thanks in advance for any advice.
