Problem statement
We have enabled realm-fallback in all tenants to support some unique scenarios where client applications pass in realms that do not exist on the auth0 side.
However, we noticed that this feature seems not to be working anymore after we migrated our tenants to the converged platform.
We enabled this feature by setting the following two options of our database connection to true:
"enable_script_context": true,
"realm_fallback": true,
Solution
Please also enable the below flag
"connections_realm_fallback": true
