I remember the dynamic updates causing problems for trying to boot install, yes. I don't recall the exact nature of the problems, but I remember that they were either fatal or harmless, meaning they would either be unnoticeable or completely block the installation with an error message.
Weird, the update for Flash Player is 2 times smaller for the 1903 than for the 1809 1809 : ~ 20MB 1903 : ~ 10MB
Very "public" indeed. Upgraded with iso to 1903 without beeing an insider, got the CU directly from checking WU.
