Same problem here. getTimeline func sometimes can be called 45 times in a row, which is insane. Also I noticed that if you have multiple widgets each with it's own separate configuration intent, even if that widget is not at the home screen, it's timeline entries are still being created, meaning that unnecessary requests are made in the background.

I have downloaded xCode 12 GM and iOS 14 GM for my device. So the problem is that widget doesn't appear on a real device in the list you get after clicking "+" button on a home screen, meaning that it is impossible to add it. But at the same time it appears in the same list and works as intended in the simulator !. I did play around with scheme, target settings and also tried to use other tips mentioned in this thread, but no luck....Other thing to note is that widget stopped working on a real device starting from iOS14 beta 8. So I really have no idea what I am supposed to do at the moment.
