We have a custom plugin, we are using this plugin since Indesign CS4. We have an option to drag & drop images from this plugin pallet into Indesign Layout. With the latest CC2020 SDK, we have upgraded our plugin from CC18 to CC2020 & it works fine on all other functionality except "Drag & drop" within text frame.

We didn't made any update to the code, the same option works fine till CC2019. Is there any known issue with CC2020 sdk for drag & drop?

Note: Drag & drop allows us to place the image at left top corner of the image frame, also the mouse pointer get transforms into "T" instead of "+" symbol, when we drag over text frame.
