New UI: cannot add items/spells from the Compendium (5e, default sheets)

Just opened up Roll20 to the new UI and I can no longer drag/drop spells from the compendium onto the character sheet. Is this intended? Is there supposed to be another way to do it?

Hi Norah, 

Which character sheet are you using? If you don't know the name please supply a screenshot.

Also, could you screenshot your search criteria and what you are trying to drag and drop so I can try to replicate it?

This is the sheet:

This is what it looks like when I try to drag & drop:

(fails for all spells and items, including those I was able to add last week. Previously there was an "adding from compendium" message when dragging over, but this no longer appears)

ETA: on Firefox. Will try other browsers / disabling add-ons in the morning when I am more compos mentis.

ETA 2: think I found an add-on which is causing the conflict, but going to sleep now

Thank you, for future reference that is the D&D 5e by Roll20 sheet. :)

In my testing there was no problem with drag and drop. 

I see you are using an Extension, please try an Incognito (Chrome) or Private (Firefox) tab and test to see if it works that way. 

Thanks! It turned out to be a userscript that was interfering with Roll20. Disabling that fixed the issue.
