HI @ChiEn, thanks for reaching out. We are on SelfHosted 4.0.4 since 2 weeks, which did not do any big changes in the Editor. Everything is still pretty buggy.
I do not think, there will be any usable changes in short- or medium-term.
So we are dropping every app now and move along to another system, which has a much better approch to fix bugs already at the base.
So no more need to track this ticket.
