@TechaSoftware FYI - I’ve had an experience working with apps of 400+ screens and they work fine
If you build the app right, number of screens per se should not have a significant negative effect on general in-app user performance.
The major issue is that app builder performance will degrade with a growing number of screens, but there’s no good workaround for that: browser has to process all these screens anyway. Moreover, I’d say it’s not just number of screens, it’s also a number of components. So the only solution is closing unused tabs / apps, having more free memory and faster processor.
