If I want to update a list of geocaches, I open the list, select all and then select the tool icon.
"Update caches using Geocaching4Locus" returns the error message:
Cannot invoke setValue on a background thread
Exception: IllegalStateException
The G4L option works OK when a single geocache is opened and G4L is selected from the cache page.
The built-in function works OK with multiple geocaches selected in the list view.
But I miss the option to select multiple geocaches in a list and 'Download Logs' in order to check on the latest found/not found status.
