The knowledge base article Custom Universal Login Themes for Applications on the One Tenant mentions that themes are not supported by the new universal login, but they are supported by the classic universal login.
Is there a plan and a timeline of when the new universal login will support themes?
And if there is no plan to support it, is there a plan to deprecate/sunset classic universal login?
I’m building an application that will need different themes for different clients and I’m trying to find what is the best current solution, but also with an eye on the future.
