Sometimes DataSet not updated, when the Task (Fetch Remote DataSets) run automatic on a given time (the feedback is task run success), but if I run this task manually the DataSet is updated successfully. No issues found in logs.
I guess Xibo have a way to know if the Data Set is changed or not. In case he feel that Data Set is the same you should see in the log a warning like “Data Set not changed and so not updated”… similar but I don’t remember the exact wording. You don’t see that because in Data Set area you still see the lat date/time of the previous update when something new was present.
I hope it will help you, otherwise you can give more information like source of the dataset.
Bye.
