I had imported service dialogs from Darga-1 to Darga-4 and noticed that I am not able to set checkbox to true by default. I have not encountered this in Danga-1. In addition, I am not able to change the logo and background image in Danga-4.
I am not sure are those bugs or due to some misconfiguration in access right or permission. Thanks.
Would also like to add that I noticed that in the dialog_fields table, all the default value that were set in service dialog are not saved.
