Hi @jycob,

which version of ERPNext are you using? Several heatmaps have become alive in the latest versions, such as customer, … (ERPNext: v10.1.38)

am using ERPNext: v11.x.x-develop (b66bde3) (develop) and Frappe Framework: v11.x.x-develop (6b600e5) (develop) as seen on the about section.

Still strugling with this…any help
