After the update to iOS/iPadOS 13.2.1 our devices are no longer usable. Every ~5 seconds a dialog pops up saying that a server identity could not be verified. Is comes with three buttons. Tapping continue or details is without any effect. Tapping cancel closes the dialog, but only for ~5 seconds.
Clearly this makes the device unusable.
Is there a way to fix the problem or should we wait for another update?
