Meetup's REST API will stop working in winter 2021 and be replaced by their GraphQL API which is already active.

It seems like there is no free tier, according to their [pricing page](https://mysocialapp.io/pricing). 
Also, the project seems abandoned for the following reasons:
 - There haven't been any commits on their GitHub repos in a very long time (1+ years for most of them). [Link](https://github.com/orgs/MySocialApp/repositories)
 - The `Early Access` buttons show an expired Typeform. There is no other way to get access to the app.
 - Their documentation page links to the same expired Typeform in the first step of getting started. [Link](https://docs.mysocialapp.io/docs/setup)
