Hi,
I hope that drag-n-drop is supported on Android app.
I don’t know that Android has native support for drag-n-drop but at least my Galaxy Tab S7+ seems to have that functionality.
↓ Example of drag-n-dropping between Samsung Notes and Supernotes
(In this case, copy-paste also did not work)
↓ Example of drag-n-dropping between Microsoft Edge and Supernotes
(Above was same on Chrome app)
thanks!
