On occasion, when controlling a presentation with the android app, there are missing slides... or, well, the slide is there but it is blank (with a little "broken image"/"broken link" type picture).
I'm not sure if this is an issue on the tablet side or the Logos server side ... the sync from the projection computer seems to be fine, I haven't had trouble making the presentation from a remote location and syncing the church's projection computer to load it, etc.
I'm not sure if the logs from the presentation computer would be helpful in this case? Are there logs from the android app somewhere that I could look at/send?
