For those interested, below is the emailed response I received from Esri:
"Thanks for reaching out… We will soon be processing and compiling the 2020 Census data for release with the Esri Redistricting solution. For now, we anticipate the final release of the data and software to happen during the first half of September. With our Esri Redistricting SaaS solution, we have to coordinate the software release with the 2020 Census data release to ensure continuity in the solution. This will be seamless to our customers and please look for email communication as the release time approaches."
