I have consulted the net but not found a solution to the following problem: I have the Oculus App running and it shows me some apps which I could download. But on the page of the App, it only says "Gekauft" (bought), and it never installs. I have 20 GB internal space and even more on my SD card. This is a Galaxy S8. I have the Facebook App running and enabled. One suggestion was to enable the Facebook App Installer and Manager. There is no such App on my smartphone.
