Hola amigos,
I noticed when upgrading some clients from sub 9.7 versions to 9.8.10 that the GlobalSettings element /Globalsettings/Ecom/Navigation/CalcProductCount doesn't get renamed to it's newer version /Globalsettings/Ecom/Navigation/CalculateProductCountForGroup causing the ProductCount property on Groups to return 0.
I changed it manually in the GlobalSettings file for those solutions so It's not a world breaking issue, I just wanted to let you know.
Best regards,
Arnór Geir
