Hi
I found a licensing comparison table between D365 Sales Professional & Enterprise in this Dynamics 365 Licensing guide (December 2021):
In that table I found the following limitation for customizations for forms and views:

Does it mean:
I can create only two custom views and two custom forms for the 'entire app acros all entities (Account, Opportunity, Contact...)'
or
I can create only two custom views OR custom forms for the 'entire app acros all entities (Account, Opportunity, Contact...)'
or
I can create two custom views and two custom forms 'per entity'
or
I can create only two custom views and forms 'per entity'
And what if I don't create a new form but customize the default Sales Professional form? Does that count as an 'custom form'?

I looked in the suggested Appendix D for guidance but could not find anything on that:
