Maestro is great. However it lacks so many important features you might need

For example, Maestro does not let you to coordinate multiple flow tests together. One test case I had is one phone initiating a call, and another answers it. Instead, Maestro prefers that every flow is self contained and will not run both in parallel reliably

I found many such limitations in its design only after writing a whole lot of their custom flow syntax
