adding to the list the use of the Databin.
immediately I hit a limit and got this error message
Databin::apierrl: Your databin entry could not be added because it exceeds the 25 kb limit. To increase your entry limit, contact us.
The "contact us" link takes me to this page: https://datadrop.wolframcloud.com/datadrop/plans.html
which says that I should have 15Mb space... more than enough. It doesn't say anything about a 25Kb limit. I've reached out to support (again)
Dear Wolfram people, you have a wonderful technology stack. Seriously. Please get your product documentation to a state where one can figure out what products, licenses/plans one needs to actually build something on it... thank you.
