We had "Today widgets" that worked perfect for a long time. After introducing the new Widgets Extension we added a Widgets Bundle to our app. Now after every app update the old widgets disappear from "Today view" and can be bring back ONLY by rebooting the iPhone.
Sometime when they disappear, in today view appears the first widget from the Widgets Bundle. I've tested other apps too and it happens every time on apps that support old and new widgets (Xiaomi Home app for example).
Does anyone have a clue how to fix that?
