I have been running Rstudio Cloud in my class for some time. Today when I open Rstudio Clound in my Chrome browser, I got a message at the bottom of my browser saying "You license will expire in 14 days." Then I googled for Rstudio Cloud licensing options but there does not seem to be any.
The licensing issue should now be resolved. If you still notice it on a running project don't worry, the next time your project stops/starts the message will go away. This was not a licensing issue related to your use of rstudio.cloud, but instead an internal validation issue.
We don't currently have licensing options available for this product, as it is currently in alpha.
