Since a few recent updates, I don't have any recent apps. They are not closed, if I want to open them manually it resumes where I left them, but with gestures I can't switch between them. I restart the phone. It works for a while (have plenty opened apps and I can switch between them), but after some time I can't switch from any app to another one. It says just "No recent items". Is this a common bug? Or am I set something wrong?
