The app have a free trial, why purchase if it does not fit your needs ?.
About the logs as I said I need them when you reproduce your issue and including a sync. So yes it’s mostly your fault if it’s empty as you do not sync with the logs enabled.
The application have tons of settings for the local device and I have absolutely no way to guess what you have checked.
So as requested:
Enable the logs then press the sync button then provide the logs that will show what you do.
