I was able to do the setup. Waited for more than 30 minutes, download has been completed as per output logs, but it didn’t run on my device and there was no error shown.
The provided information is not enough to determine what might be causing the problem. With this in mind, I recommend that you open a new issue in the Sidekick GitHub repository and share the Sidekick logs there. This way the Sidekick development team will be able to investigate this issue in more detail.
In Sidekick the logs can be accessed from Help → Show Logs.
