Expansion is disabled if there isn't enough space on the page to expand the widget, so make sure you have enough space.

Ah, yes that is exactly why expanded mode is part of the beta feature.

There is no clean/easy way of pre-determining the actual size so there is no automatic way of calculating the height. However the bigger issue is the content of the widget don't update for some devices on iOS 13 which is why you are seeing only the top portion of the widget. I haven't exactly figured out how that gets cropped.

Okey. Thanks for your work!

Reopening issue as it'll need to be fixed at some point.
