Hello,
Many of us got familiar with Datacamp which uses the ipnyb files that could run as anaconda on the cloud.
But recently an update prevents free profiles from making more than 3 workspaces and if you have more a message appears that you have used more workspaces than required.
Drawbacks of new limitation:
If someone has multiple projects, it could arrive that Datacamp interrupts work or even delete some workspace or let them inaccessible or prevents from running the code which seems not the ideal solution at all.
