I have an app created containing about 25 screens, data sources are 4 sharepoint lists, for some reason when I try to duplicate a screen, it takes more than an hour now for it to complete. It does not work, i get not responding page then after, also then i see a weird out of memory browser page and then have to reload everything again.
What could be the cause here? The screens have sp edit forms with necessary fields tied to sp list, why is it insanely slow? any thoughts?
