Adam When I tested Enhance I ran into the whitescreen a few times too outside of emails. Probably from connection issues as well.
From a UX/UI standpoint this is bad for customers and a small reason why I don't use enhance in production. Will there be useful error messages soon instead of just a white screen sometimes? It seems pretty straightforward to display an error page with maybe a code that can narrow down problems.
If a customer were to run into logging into a white screen and it suddenly starts working again, from their perspective the panel is unreliable and therefore so is the hosting.
