Hello L.,
Do you think of that:
@startuml printscale weekly Project starts the 1st of january 2021 [Prototype design end] as [TASK1] lasts 40 days then [Testing] lasts 30 days @enduml
@startuml printscale monthly Project starts the 1st of january 2021 [ Prototype design end] as [TASK1] lasts 40 days then [Testing] lasts 30 days @enduml
It seems depend of the printscale or projectscale...
If that can help,Regards.
