Hi Both,
Thanks @PSYresearcher - I think this information from learnt experience is really helpful.
For some further context, when we take our data online we enter a whole new world in that the saving of data is also dependant on our participants waiting for the data to save on their end. As @PSYresearcher says, having a really clear end screen can be helpful here.
There are some additional threads also relating to this matter that might be helpful.
