Hi @RazikM ，
Every time you open your presentation, the report page reloads into the add-in, bringing fresh data from the Power BI service. There may be times when you don't want this to happen, and instead would like the data to remain static. For this you can use the Show as Saved Image option. Show as Saved Image turns the current live view into a static, non-interactive image. Then, when you next open the presentation, you'll see the static view you saved.
To restore the interactive view, select the Show as Saved Image option again. The live report page will reload in the state it was last in, but with the latest data from Power BI.
