After update I can not see my contacts at call log list.
Still have all my contacts but does not show name when someone call me or if I will call from call log I do not see contacts I already had.

Go to phonebook, filters, and make sure they are selected.

You can also try to boot on safe mode and see if you experience the same issue.
