My local bank has a native app as far as I can tell and it regularly takes over 10 seconds to get past the login page. My credit card (Discover) app somehow won an award for best UX in the industry and still takes over 5 seconds to log in (both of these are with Face ID by the way).
Contrast this to Robinhood, which jumps from cold boot to main screen in about a second.
The problem is not the frameworks, it is poor development practices. Until the big guys learn that outsourcing critical software is a stupid idea, the next generation cool kid apps will continue to eat at their customer base (until they become relevant enough to be bought out by the big guys, and the cycle repeats).
