Michael,
I have had the same problem as you after the last two updates (not this time though). Fortunately, the problem ceased to exist after a couple of days each time. In the first days after an update I would have to download some app everytime I restarted the phone. After a week or so, the problem was miraculously solved. Before that, I once called support, but they couldn’t help me either, although they were aware of the problem - at least one FP employee was affected too. Maybe you wait for a week or so and see whether the problem persists…
