Program Changes to VST3 instruments (here Halion7)

Hello from Germany!
Since the Steinberg forum is not helping, I would like to ask here: Does anyone also use Halion in Gig Performer? As of Halion7 there is only one VST3 plugin, and unfortunately it ignores the program change commands coming from Gig Performer!
With Halion6 as a VST2 instrument it works perfectly.
Unfortunately, the problem cannot be solved in Halion7. This is probably due to the VST3 standard, as I understand it.
Is there a solution in Gig Performer that someone may have already found?
Many thanks for your help!
Claus

As I know there is no workaround for the PC message issue with VST3.
In many forums there are posts about that issue.
