Might be an issue with a previously release. Not sure which you're on. I would create a support case and pull the logs.
In the meantime I would just append ?:refresh=yes at the end of the URL string so that you don't have to manually do if every time.
You might try adjusting your "Configure Tableau Server" settings too
Data Connections> Refresh Less Often if it isn't already to see if it has any impact on your situation.
I'm on 8.1 but I've tried to Data Connections> Refresh Less Often and Balanced but neither fixed the problem. Is there a way to have the URL ?:refresh=yes always be active for all users using the Dashboard?
Not that I am aware of without hacking Apache
You'd want to Refresh More Often
Haha yes, what I meant :-)
I have this exact same problem. Adding "?:refresh=yes" to the end of the URL is not going to work since people are opening the view through Tableau online and not through saved web links. Is this a known issue that will be resolved?
