How can I refresh the native app

I’m facing an issue that sometimes my script fails because the element doesn’t load to page source. I tried to apply explicit wait for the element but that is also not giving me the consistent results. Can you suggest me the possible solutions for this?

One of the solution, I can think of is refreshing the page. But, I’m not sure how we can refresh the native app’s page.

Can we fetch the app package and app activity for the screen available on the device and relaunch the app with the same package and activity? if yes, can you please tell me how?

Or If you have any other solution?
