Not sure if this is the right place to give some feedback about Astra.
1) DataModel notebook: when running the setup CQL script the 1st time. the schema was created but tables were not seeded with data but there is NO data. 2nd run and everything is in order could continue the exercise.
2) AdvancedDataTypes Notebook: the pane containing the CQL setup: cannot scroll past line 214. Using Chromium browser Version 83.0.4103.116, Ubuntu 20.04
BTW, Congrats to the team, the notebook content is very well designed.
