Question: Which "Open link" block conditions lead to the "On error" state?

@Mark reading this thread should make it clear that the first circumstance is not met no matter what. Something your dev team should look at? Would you like me to open a bug report?

Thanks

@Deluxe, from this thread it appears that there might be a bug in the case that there are no registered apps to handle the provided URL. Please do open a bug report.
