This might be nothing, but I found myself doing this twice in a row now and wondered if it has any consequences.
After an update, there are two notifications simultaneously:
- "Finishing update..."
- "App optimization completed. Press to restart all apps..." (not sure about the exact wording)
What happens if you click the second while "Finishing update..." is still shown? The first notification will be gone directly after clicking the second, but will it have aborted that process and will it have consequences for the update process?
