Apps are refreshing their content on iOS and iPadOS

Hi,

on my iPad and iPhone using Apps like Facebook, PdfExpert etc. the content automatically refreshes if I switch to another App and then go back to the the first App to continue where I left. They have refreshed so I can't continue where I was, or at least I have to wait a few seconds to refresh content before I could continue my activity. This problem drives in crazy and I was a huge fan of apple but now I’m thinking around not to use iPad any more, because I can’t use multiple apps parallel if they lost their content at a switching. All my Apps update when I bring them back to front and they are loading their content again.

Any idea of what to do?

I have search and searched but can't find any solution for this. Shutting down “app background refresh” in the settings doesn’t solve this problem. I can’t understand why aren’t online forums full of this problem?!

Hope someone can help.

Kind Regards

Agnes
