Grasshopper hanging in Revit 2019.2

Hello
Is anybody else having issues with grasshopper in Revit 2019.2? When I load a larger script (that works fine in native grasshopper) it slows right down and every action takes 10-30 seconds to complete. Adding nodes, moving nodes, all cause grasshopper to pause with the blue wheel spinning. It seems like it does an action then Revit takes a while to process?
I’ve tried it on another computer with 2019.2 and the same issue. I have thoughm tried the same script in 2017 and it works perfectly. no hanging at all…
thanks

Could you please try disabling the Grasshopper preview in Revit?

Brilliant! That works well. I see that the Revit 2017 add-in doesn’t have the preview which is probably why it didn’t hang.
Thanks for your reply Kike!
