When you launch an installable cloud app at the client side, Cloud App Launcher is first downloaded and installed, and then the app files. The download log of all the web files can be found at the client side:
For Cloud App Launcher without background service, the log file CloudAppShell.log is at %LocalAppData%\Launcher\log.
For Cloud App Launcher with background service, the log file CloudAppShell.log is at %LocalAppData%\LauncherWithService\log.
The app file download logs are at %AppData%\PBApps\Applications\[appname]\log.
