undefined is not an object (evaluating locale.replace) when upgrading to SDK 35 (using ExpoKit)

I just upgraded to SDK 35, and am now getting the issue below, which seems to be referencing Expo’s own Localization code. Any idea what’s going wrong here?

undefined is not an object (evaluating 'locale.replace')

Somebody else posted about this recently. Apparently it’s only a problem on the Simulator. Is that the case for you as well? Also what is the version of iOS that this happens on? @herbertlim posted on the other thread that he suspected it might be a problem with iOS 13.0.
