Hi Razvan ,
While using the Refresh page in microflow, some things should be considered. For example, you changed an information in a popup using microflow, and there are refresh page and close page activities in microflow. In this case, you cannot see the refresh feature on either the popup page or the 1st page. So you can try using the refresh page activity after the close page. Or you can try to refresh your 1st page using a button. If this method works, you can configure the refresh accordingly. I hope it helps
Regards
Ridvan
Could you please show us your page setup and your save mircoflow? I just recreated your setup and refreshing the page param of your first in a regular change action worked just fine for me.
